Fanuc Oi-Mc Control Sub Program Call?

I have a long program that I need to let run un-attended over the
weeekend.

Because of the half-assed system we have for loading our programs here,
I need to run this program in 2 parts.

I will be DNC-ing the main program off a Flash memory card. Can I call
another program off the card as a sub-program (M99) during this DNC
run?
