If the goal is to make hundreds of holes, as with my machine with a field of 3050*1030 mm, then to allocate in FC each hole - you can die.
To solve the problem, there are reasonable ways in g-code - firstly, the use of loops and subroutines, and secondly, the displacement codes of coordinates.
The number of lines in the program is then reduced to tens, hundreds regardless of the number of holes. And it makes sense to learn to do it yourself, not trusting blindly FC (as any other program). Not to mention that creating a volume model for such primitive works and making programs in it is not quite an effective waste of time.
At me, with use LinuxCNC (under Windows with their regular screens of death of different colours all the same it is very risky to work, because Linux, because LinuxCNC), there is a subprogram of milling of a line of a circle O1, it is caused by the necessary number of times the subprogram of milling of a circle, and it is called in the necessary place it is necessary number of times simply with instructions of the center coordinate and depth. The call line is approximately so, on each hole -
o<otvp> call [30] [34] [99] [40] [6]
30 - depth
34 - X coordinate
99 - Y coordinate
40 - hole diameter
6 - cutter diameter

I think it is also better for you to do such work simply in a text editor taking into account how your machine control program processes g-code
