As far as I see, there is no way to import sessions in any way.
I used CStimer on different devices and now I can't put the sessions from the one device to the other without removing the existing sessions.
Also, you can export sessions as an CSV file but you can't import a CSV.
You can import session without reset other options or sessions by EXPORT -> "import session(s) from other timer". It also works for cstimer exported files.

I'd like to have a wayto do so.
