Any way to update XtreStoLite without wiping? (getting bootloop if I don't)

Hi

I tried to dirty flash XtreStoLite 2.2 from 2.0, but I got a bootloop, so restored to 2.0.

But I got so many things on my phone that it takes an hour or two to set up, so is there any way to update without doing a factory reset every time an upgrade is available?

Thanks in advance
