Facility Control

I have 'Take Crosspoint' buttons on a custom grid file and rather than typing in the name every for every button that I build, I'd like the source Name of that input of the crosspoint to be populated in the button name. 

Is this done w Logical Sources somehow? 

Determined where the code is for the name below after I've manually input the button name to "autoname", but just need to find the syntax for something other than user entered string

<button buttontype="push" height="59" left="234" name="autoname" top="61" width="388">

If there's another way to do this i'm all ears. 

for clarification, this is for an ultrix-fr5
