Template Consistency

I have a pretty intricate part template that I would like touse asa format for an assembly template.  This particulartemplatehas an embedded excel spreadsheet that controls a varietyofreference planes and axis'.  I do not want to redo any ofthiswork but I can not figure out how to copy and paste thefeatures...In pro/e I would create a user defined feature andsimply insert itinto the assembly... I can't figure out how to doit in SW sp4.... 

any ideas?  what is the best way to move features fromonefile to the next?  

To Simplify the problem...If a part contained an offset planehowcould one bring that plane (along with it's referencesandproperties) into an assembly with out re-creating theoffsetplane....

thanks!!
