Hello,
I am working on a custom project with version 4.24.1 source build and I wanted to know how I could add a custom class to the ‘Pick Parent Class’ editor UI under the ‘Common Classes’ category. I have been unable to find any documentation on how to do this. Can anyone point me to in the right direction? Attached is an image of the UI I am referring to.

I want to do this in order to speed up my workflow because I will need to have quick access to certain classes within my project and it would save some time to add a few classes to this list. Thank you in advance for the help.

I would like to follow up with this question because I was able to find an answer, and I will make a tutorial for it as well on my YouTube Channel this coming week; I will post on this thread again with the link.

The quick answer is:

In BaseEditor.ini, there is the following:

; Class picker dialog settings
; LocText refers to the localization id for the descriptive text to show next to the icon in the picker

+NewAssetDefaultClasses=(ClassName="/Script/Engine.Actor", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/Engine.Pawn", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/Engine.Character", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/Engine.PlayerController", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/Engine.GameModeBase", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/Engine.ActorComponent", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/Engine.SceneComponent", AssetClass="/Script/Engine.Blueprint")

What you can do is go to your DefaultEditor.ini and add the following lines:

[/Script/UnrealEd.UnrealEdOptions]

+NewAssetDefaultClasses=(ClassName="/Script/Engine.Actor", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/Engine.Pawn", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/Engine.Character", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/Engine.PlayerController", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/Engine.GameModeBase", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/Engine.ActorComponent", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/Engine.SceneComponent", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/Hero.HeroGameplayAbility", AssetClass="/Script/Engine.Blueprint")

The option in bold is my new category that I wanted to add. Here is what my Pick Parent Class dialogue looks like now:

It took a lot of digging in the source code, but I was able to find what I needed. I hope this thread helps anyone else looking to achieve the same thing. Thanks again!
