As @Nr.5-need_input says, the subroutine isn't geared up for that.
Instead, you might want to look at this How List Active KM Macros With Their Keyboard-Triggers? and incorporate the solution for that with this subroutine in order to achieve what you're asking.
If this is way off the mark you might want to explain why you need this as there may be other, better approaches to getting what you want.
EDIT:
Another topic that I didn't link to because it didn't provide a solution has just been updated by @ComplexPoint to include a macro that's worth looking at. Check it out here: List Macros With HotkeyTriggers - #5 by ComplexPoint
