Get AnimNotify Preview in Animation Editor

Hi, so I have a custom AnimNotifyState that spawns a hitbox actor (it’s basically just a collision box), with a couple of variables.

When I add the Notify to an animation I can edit the variables just fine and it works ingame, but I can’t get the preview in the animation editor which makes the editing of the scale and offset of these hitboxes a pain to tweak, I basically have to click play, check them, stop, edit the variables and repeat that process.

How do I get these hitboxes to show up on the animation editor?

Thanks in advance!
