I tried this Larry and it's not working for me. I have Mercury, which is really what I want to update, that expired in Sep2019. I also have AR Saturator that expires in Jan2021, AR Studio 3 that expires in Dec2020, and Inspire Instrument Collection that expires Dec2020. WHen I select Mercury and any of the three that hasn't expired, it jacks the price up by $140 and tells me:
Your Waves Update Plan exceeds the $240 cap due to either selecting multiple identical licenses, or the coverage you’re about to purchase is for more than 1 year for some of the selected licenses.
So, I'm back on the fence trying to decide if I want to do this now or next year.
