I'm using 16.5. I started to make a new symbol with one part/package. I have about 100 pins, out of 250+ pins, placed on this package. Now I decided to add a second part and make this a two parts/package symbol. I clicked on OPTIONS/PACKAGE PROPERTIES and I can change the Parts per Pkg to 2, but the Heterogeneous radio button is grayed out. If I create a brand new part and copy/paste my existing part, the pin names copy over, but the pin numbers don't. Is there an easy way to add a second part and make this a two part symbol? TIA.

Thanks Oldmouldy! I actually did the RMB>Split Part and saw the spreadsheet. I knew I could change the number of parts and add pins, but I didn't realize that the part would then save as heterogeneous, so I never tried to save it. I abandoned my effort one step too soon! Thanks for all of your good answers to this forum.
