Different Supports on same object

Hey guys,

I’m having trouble printing my Stellar Blade figurine, cause the arm keeps falling over while printing.
For better surfaces, I’m trying to use PETG as interfacematerial and there I think, is my problem.

Is there any way to use different support-setting for the same object? I tried modifiers, but this is not what want or I didn’t got it…..

Is it possible to print the supports in the red circles with PLA-interface for a better stand of the arm and the supports in the green circles with PETG-supports for better surfaces?

I’ve already googled it, but didn’t found anything useful.

Thanks and best regards
Christian
