Allowing texts in "Attack per round" input field in NPC/Creature sheets

[doumoku]

Right now, we have the "Attacks per round" form in the NPC sheets and the creature sheets.
This works for most part, fill in the set number of attacks and we're done.
However, I find some instances where the creature have random number of attacks (such as 1d6+2 attacks) per round
and the sheet would not allow such cases as you can only input numerical digits.

This could be fixed by allowing texts in the said form.

Context.

I know this system is not fully combat oriented, but as a Keeper I would like to not refrence the books during games too much so...

Possible Implementation.
