upgrade single buds?

[cinatic]

Hi and thanks for your work, it works great. I wonder if you maybe have an idea if my following problem could be solved. I have 2 pairs of wf 1000xm4, 3 on 2.0.1 and 1 on 1.5.0, is there a way to get them all to one version?

I would like to know this as well. Maybe there is a way to fool the app, that it thinks that both earbuds are connected?
