The "To Coda" instruction in pallet

A lot of my jazz player friends ask me why I haven't put the coda graphic (circle with cross-hairs) in the middle of the instruction "To Coda" - i.e. To "graphic" Coda. It makes it obvious and helps greatly when sight-reading and for most of the guys it is the de facto way of presenting the instruction.

I can do this the very long-winded and time-consuming way by editing the To Coda instruction and inserting a special character, then increasing the size of that character, so is there a way of adding my edited version to the standard pallet, or making a shortcut?
