Hi there. There's no way to do that currently, and it's also the first time I've seen this suggested. It's related to, but different from, being able to do bit modifications via a supercontrol, but... it's different.
About Named Ticks: Note that you can do the better stuff using the Edit Text box. I typically figure out what I need to do in Excel, get it to text, and then bring it over.
Thanks for the suggestion!
