There is no documented way to do this in DashBoard or guide.
It is possible to send Mnemonic name changes to Ultra via RossTalk - Note unlike TSL UMD protocol this will update the source Label in the Input Table as well as the panel mnemonics.

lists the commands with the MNEM command being the one you would send from DashBoard. You would need to build a DashBoard Custom panel of some kind that is going to be tied into your Labels and I speculate some kind of Router I/O Panel that would need to be running that will you will add code to send updates to the switcher based on changes to specific outputs.
