Separate Raft Selection

**Is your feature request related to a problem? Please describe.** I have auto printing on my printer and for ASA I have to use HIPPS as a raft so it doesn't stick to the plate. The issue I'm having is if I need supports, it won't generate the supports on the raft. It tries to make the supports off the raft on to the plate. This is the case if I want supports to print in the same material as the object. It will make supports in the HIPPS on the raft but I don't want to use HIPPS as it waste it more an because I'm not using a purge block with my setup, it will mix materials in the print. **Describe the solution you'd like** Add another option to choose what filament for just the raft. Also have an option to make supports print on top of the raft if it is a different material. **Describe alternatives you've considered** There really isn't another option that I can think of. **Additional context** To further explain my setup, I have Farmloop stage 2 on my P2S and the raft is the only way prints will come off the print bed properly with ASA. <img width="2419" height="1479" alt="Image" src="https://github.com/user-attachments/assets/ec9919b8-a384-4c76-8da8-e06702d35ae7" />
