Rigging "Insert Tool": how to replace a truss once it's placed?

[VClaiborne]

 I’m new to the Rigging tools, so please forgive my simple question..   I’m attempting to use the insert truss tool in VW and searching for the best way to replace a truss symbol with another symbol once it's been inserted into the drawing.. 

 

 For instance, I picked a piece of 20” box truss originally that was 2’ in length, and wanted it to be a 6’ piece instead.  Is it easiest just to delete the wrong truss?  I don’t see a way to ‘replace’ like you can with fixtures when you want to change a selected fixture to another type..  

 

Thanks!
