How to permanently update/create Uassets in the editor during runtime?

Okay, sorry about the long delay in posting here. So the Editor Utility Blueprints that you mentioned are actually a great system, and they are working out perfectly after some testing. Now, I am having to use a plugin to actually get the data to populate into a data table because Epic’s native support for editing data tables is absolutely lacking.

This is the plugin I’m using:

But I got it working, and it’s very very nice. For anyone else who tries this, if you are adding any significant number of rows or data to a Data Table, make sure you don’t have it opened up in a tab because that will REALLY slow down the process or just lock up the editor, so make sure the asset is closed in the editor while you’re editing data.

Thank you so much @3dRaven, you have seriously helped me out here.

For others looking to manipulate editor assets (Not just Data Tables), here is the intro to Editor Utilities that helped me out significantly:
