Yes, follow the instructions here https://surfer.nmr.mgh.harvard.edu/fswiki/PetSurfer
when you use mri_gtmvpc, specify the structure(s) you want to rescale by with --rescale Id1 <Id2...> where Id1, etc are the segmentation ids as found in $FREESURFER_HOME/FreeSurferColorLUT.txt (note that they have to be in the gtmseg.mgz file)
