Variables for Macros

It would be nice to allow variable input for macros, for instance macro name: toHIt "/roll 8d10!>x" we would then be allowed to enter #toHit 7 which would expand to: /roll 8d10!>7 not sure of the technicalities here, but it would be very nice. I'm sure multiple arguments would be more of a pain but even more useful like: macro name: toHIt2 "/roll xd10!>y" we would then be allowed to enter #toHit 6,4 which would expand to: /roll 6d10!>4 A system like this would greatly streamline a good many of common rolls for players that can slow down the game flow.
