Any way to hide Background Material in Widget Blueprint Button when being selected?

Hey all, I’m trying to implement custom widget blueprint buttons into a menu and I’d like to get the buttons to show as yellow when being selected/hovered.

I have the default material for the button set as the Background material of the button and the material I’d like to have show when being selected set as the Border Material.

Which gives me what’s shown in the clip below with the Background Material covering the Border Material.

Now, I don’t know if it’s even possible in UEFN to get this to work as intended, so any info would be greatly appreciated. Thank You!
