Grbl Command to call sub-routine

Does Grbl have a command to call a subprogram? For example if the command was P[file name]. The main program would include.

G0 X10 Y10
P[key-hole]
G0 X100 Y100
P[key-hole]

The reason for this is if the key-hole program changed I would only have to edit one file, instead of finding every program that includes a key-hole and editing them.

No.

It is quite memory-constrained, so no variables, loops, branching, &c.

(I believe bCNC supports that)
