"step and repeat " with Flashcut

I have been working with Flashcut for a few days.
How do I do a program in multiple locations on a router table?
They use G52 for a local coordinate move, but, it looks like that
will work for only one location.
Will I have to create my files in rel {G91} then use them as
subroutines?
I am familiar with G92 to reset000 or G54-59 for fixed offsets.

thanks
Carl
