Yes but you’d have to switch between S1 and S2 each time you wanted to change. Not something that most folks would consider given the time and effort needed.

So, essentially, no. The effort involved between switching would be considerable, and last time I checked (it’s been a while), you needed to have an S1 device set up to add/downgrade the others to, which means at least one S1 device that never ‘moves’ to S2. 

I missed/forgot the need to have an S1 device available to initiate the downgrade. 

I don’t ever do this, but I ‘think’ it’s still a requirement. Perhaps someone with greater knowledge with the process these days will chime in. 

Thanks guys.  I’ll continue my search for an easier solution.
