I am having a difficult time with the "Save Bodies" feature in regards with the naming the body for multi-body parts...  Basically, I'll have a multi-body part and I will name each of the solid bodies a part number.  However, if I make a change to anything within the multi-body part, the names that I assigned to the solid bodies will change automatically.  When this occurs, I get an error with the save bodies feature and the link between the external reference part (parts created by the save bodies feature) is broken.

Is there any way to avoid having solidworks automatically change the solid body part name when I make a change?  I believe it is related to the inherent naming convention when solid bodies are recognized by the last feature name. 

Thanks, I appreciate your help.
