Decal in blueprint - with boundingBox visable?


I would love to create a decal template in blueprints for our layout guys.
It’s working, but the bounding box you see when creating decals the normal way isn’t visible when you create your decals in blueprints.
Without that its hard for the layout guys to use it, so we end up creating tons of decals with separate material instances to get the control we want, instead of just a couple of “master-decal-blueprints”, with controls like multiplying the alpha per decal, and so on.

Any help on getting the bounding box of the decal visible when creating decals in blueprints would be highly appreciated!
