The thing is... often when players do this kind of thing, it's bad tactics and accomplishes little. You would be better off to just swing your sword again. And knowing when to change it up and when to swing your sword again is not easy and requires a level of system mastery. For players without that level of mastery, hack and hack again is the wisest and most reliable course of action.
DMs can alter this, somewhat, by allowing special benefits to improvised actions. But this, again, requires a level of mastery for the DM; you can get yourself in a lot of trouble by making an improvised action so good that players start using it as their new default.
