Switching to Avast Ultimate

I have various licences active now. What I would like is to purchase 3 years of Avast Ultimate for single pc, and 3 years of Premium Security for single android device. Is it possible to do some kind of a merger of subcriptions and get a discount on the purchase of “3 years of Avast Ultimate for single pc, and 3 years of Premium Security for single android device” based on the active licenses I have right now?

Thank you for your time.
Boris
