Linking fields to partial Layout names.

[AndrewPZV2N]

I know how to link a field to the full name in the layout.  Is there a way to only collect the first few letters/numbers?

Example: Layout named "S1  Device Locations"  Can I make a field just to show the "S1" part of the layout name?

Thanks that helped!  Specifically I used the diel expression: $(substr,$(getvar,ctab),1, 3)
