Can I get Fraxel Dual, subcision and filler in the same session? (Photos)

When asking my dermatologist if I can get Fraxel Dual, filler and subcision in the same session, she told me no. They have to be 4 weeks apart each. She then stated its too aggressive for one session and will not even perform Subcision and Filler in the same session. Is she correct on this or being overly precautions? What can a client (me) get in the same session for rolling acne scars and what would they start with first?
