Printing Support Interface Layer From a Different Material

I have a MK4 / MMU3. I’d like to print the support interface layer from PLA if the main object is PETG (or vice versa). This is to facilitate a clean and easy breakaway of the support material from the main object.

How do I do this using the Prusa slicer?

Thanks,

Tom
