Parameter text edit.

I want to separate a mark into two separate parameters. For example the mark AHU-23 to two separate parameters, one that reads: AHU and the other: 23

This would have to be transparent to the user. Mech guys are used to a tag that has AHU over 23 with a line between but linking in their data into the electrical model is useless when they use two separate parameters for AHU-23. AHU is not unique and 23 isn't either. They're too stupid and stubborn to do it any other way.
