Orca slicer does this with support_interface_not_for_body option. https://github.com/SoftFever/OrcaSlicer/commit/9719fa81ef202e307d0188d485997e4c35c234db
I am encountering this same issue and it is causing supports on my prints to break. Here is an example screenshot with PETG in orange and PLA in pink.

Description of the bug
Tree like supports are breaking apart when using a support material for support interface only.
Support material adhesion is usually significantly lower than the main material. Think PLA+PETG, HIPS+ABS. This makes nice snapp-off supports.
Only specifying support material for support interfaces makes for less toll changes faster prints. However PrusaSlicer sprinkles in the support material into other non-interface supports at the same layer. Which wreaks havoc for tree supports that need significant rigidity during print.
Describe the solution you'd like Only apply this setting to support interfaces, leave supports with the main filament. This would not affect print speed, as each layer typically has at least one main filament being printed.
