PermissionRepair trying to achive 755 for directories and 644 for files but files are always execute?

Hey community!

Trying to figure out how to set an ACL's and for a bonus use PermissionRepair to update files migrated from our old Unix storage to Isilon.  I seems like there is no way to target files vs dirs and if you use an ACL that has dir_gen_read and run PermissionRepair Inherit mode it will set all files executable.

Does anyone know if there is a way to do this? Like what the capital X does in chmod:  chmod u=rwX,g=rX,o=rX

Thanks!
