one job, multiple files, one directory

Is there any way to split a job into multiple files, not including the "designate one directory as a working job directory for everything" ?  I want to keep each job's files in separate directories, but linuxcnc doesn't seem to look in the same directory as the calling file, for subroutine files.
I really just need to do a series of G92 (or G10L2 etc), run file A, G92, run file B, etc.
