Hi MattDMBA,
My name is Raffaele. I am a fellow Microsoft customer and expert user here to help.
Not sure I understood correctly but are you referring to SPC for Excel add-on? https://www.spcforexcel.com/spc-software
If yes then I recommend you ask them the related question because unfortunately third party add-ons functionality are out of our knowledge.
Hope the information provided is useful. If the issue persists, reply here and we will be glad to help you.
Thank you for posting in Microsoft Community.
Kind regards,
Raffaele
