Dumb Question - Arbitrary DCs on a hotkey

[jkb619]

Would like to create an arbitrary 'Dex save' macro for the hotkeys...have it prompt for the DC value (or even prompt for DC type 'and' value). How would I do this?

I 'think' create an NPC/Hazard with saves attribute? And drag each save category off onto the hotkey
