Path: Selecting partial holes for drilling operation

Path: Selecting partial holes for drilling operation was created by fletch
My mill is very nearly done so I foolishly offered to do a 'small' project for my daughter's boyfriend as a thank you for getting a very old engine running... Part of that gift is a GT2 gear in the shape of a 'C' (see attached screenshot - I haven't uploaded the FCStd because it's a small cog in a larger project but I can recreate it if need be).
My cunning plan for my first(!) Path job for the teeth was the following:
1. Drill ~ 150 2mm holes around the circumference
2. End mill (5mm) to within 0.1mm of the circumference
3. End mill (2mm) to clean up and put the 'fillet' on the teeth
Feel free to tell me if this is not a reasonable approach, but I'm struggling with step 1* - I cannot select the 2mm inner radius of the teeth for a drilling operation. I tested this with a slot in another part and was able to select the end(s) of the slot for drilling, so is this possible on what is effectively an un-closed 'slot'? Or rather, 150 of them (will I have to select them individually?).
My workaround would be to create a dummy model just with the holes but that feels like cheating.
Any thoughts and advice would be welcome.
* I will probably also struggle with steps 2 & 3 when I get to them...
PS, I couldn't find a 'Path' category - would there be any mileage in separating some workbenches?

Moved to "CAM" section.
"Path" is a FreeCAD addon for generating gcode used in CNC machines, and as such it has nothing to do with LinuxCNC, till you need that gcode to be run by LinuxCNC.
I use Freecad a lot lately, i need a mount or a part, design, export, slice, print!
Did you notice "slice"? I use for 3D printing, never used Path, yet, so can not help, sorry.
There are some here, pretty sure one is developer of Path, so he might be a much better help than me.

No, not deleting it, there are more people using it as time goes by, so leaving it here, if yoi figure it out please do report back, it might help others here ... or me when i build my mill, whenever that may come to pass.
Thank you.

I've started a topic in the *correct* forum...
Hope your mill happens soon.
