Macro covering 2 runs

Hi Hi

i am wondering if its possible to have 1 keybind, with a macro that will cast either Chimera Shot or Explosive shot, depending on what Rune I have engraved.

Any ideas?

I actually have 2 pairs of hands, and swap them to avoid constant engraving but atm its on 2 different keybinds

/cast Hands Rune Ability

Epic thanks!
