Attribute hint for Type widget narrowing

[MrBrax]

What can't you do?

Would be useful to have an attribute for when you have a [Property] with a Type to be narrowed down to a single type and its derivatives.

In my game resource, I use a Type property to store its DTO, but every time I need to change it to the only type and derivatives that work with it, I have to either search or go through this large menu.

How would you like it to work?

Probably an attribute of some kind

What have you tried?

Can't do anything

Oh, that would be nice.
I also needed that so I made my own controlwidget and an attribute TypePicker(baseType, onlyConcrete) but an "official" would be better
