Yes, but IMO, unless you are absolutely sure of what you are doing,XT32 curves are best left unmodified.
I haven't done experiments on XT32 but have tweaked around a bit on manual adjustments with Anthem room correction (ARC) results.
Long story short, the best results were obtained leaving the original results untouched.
XT32 is a fairly high resolution solution and it's generally considered to be at tier II of room corrections along with DIRAC and ARC.
Trinnov is considered to be the best amongst the lot but it's quite expensive to get
