Is it possible to select multiple face for the helical operation at once?

I have a part that i want to cut, and im asking for future reference, is there a way to select a large number of holes for the helical operation? Like a click and drag? i have like 50+ bolt holes that need cutting, but I was just wondering if there was a less tedious way

at present, only holes for drilling are auto-detected. it’s on my todo list to improve that (allowing arcs) and the selection process for cylindrical faces suitable for helix cuts. if you can share your model with me, I can use that to test any code improvements. thanks
