Changing an ammo-type's repeat-count with research?

[Duane]

I'm currently working on a mod, and I have several weapon trees. Currently, I have a freefire (not targetted) laser rifle. It fires one laser in a cone of roughly ~20 degrees. From messing with values, I've found that rather than increasing the firing speed on such a weapon, it would be much more beneficial (mostly on ammo) to increase the repeat-count (number of lasers), rather than firing speed - but I can't find out how to do that with a research, because repeat-count is nested in action, and referencing anything in action doesn't really make sense to me.

Is increasing an ammo-type's repeat-count possible with research?
