Inserting a truss that has been modified in CAD Detail Management into my plan

[REOWENJR]

HI 

I have modified some trusses in the CAD Detail Management in CA X17 but they are not presently inserted into my framing plan. 
1) Is there a way to select one of these modified trusses and insert it into the framing plan?

 

2) Is there a way to switch a one type of roof truss with another? IE If I have  truss TR-1 how can I swap it with  truss TR-3 which is in my CAD Detail Management?

 

Any help or suggestions will be greatly appreciated.
