Not necessary, but...

...you've just described the EXISTING drill cycle. Why not use it?
(see i still know no gerber because you don't tell me where to read ;-
) )
I have literally a hundred or so books on the subject of gcode and
cnc. Along with many machine control programming and machine owners
manuals. What I know I've learned over MANY years from MANY
resources. I don't have a great resource for reading about gerbers
online... But you could start at GC technologies, and see where it
leads...
FWIW, gerber and Gcode are like a siter and brother. From the same
family, very similar, but definitely different. And just like a
sister and brother, who become MORE different as they grow; gerber
and gcode have diverged further (farther? Troll?) as time has gone on.
You can read about gcode at several sites online. Best to just do a
search of "G code" and "Gcode".
Peter Smid's book CNC Programming Handbook (about 35 bucks) is
probably the best out right now, but just like all the others, it has
mistakes you won't catch unless you're familiar with the subject. But
it's worth its cost, IMO. Mike Lynch is another writer on gcode whose
books are easy to follow. MANY cnc and Gcode books and online
resources are TERRIBLE.

Yes.

Yes. You have just described a macro<G>
