Can't find a variable that supports images and sprites like native widgets do?

As I said, I need a native UE solution. Custom C++ code will not be viable for this.

I’m unaware of any way to add allowed classes to blueprint variables, unless you have any ideas about this?

If the answer is: there no solution. Then I’m just going to end this, and ditch sprites, and figure out a better naming convention for UI textures.
