hello everyone,

I have read that HIPS can be used to create raft parts made with ABS, HIPS given that dissolves with the limonene.
I would like to know if anyone had tried to do it, and how,
  since ZSuite does not allow to do this
thank you

There is (currently) no way to change filament selection at different points in a print (maybe this would be a nice feature?) so as you said, it really can't be done with Zortrax. 

I think the HIPS you are thinking of is different than Z-HIPS. Different formula.
