Trying to determine best practice for toolbox parts inside PDM.

I have my toolbox setup as #2 described here:

I have a number of custom properties setup as configuration specific (Part Number, Description, Etc.)

I'd like these to be duplicated on the '@' tab as well. My columns display info from the '@' tab.

Can this be done with the datacard? Transition action? Dispatch? Custom Task Add-in?
