I just wanted to pass my regards to Paul for the EFILive software.
I'm in the same position as Taz, the new CAX handling is kinda inconvenient, particularly when you want to do the same things as you described however the public explanation Paul's given is one of the reasons EFILive is a premium piece of software. It is one of the few tuning tools I use that doesn't have weird bugs that are unresolved for months/years or indefinitely.
Really appreciate the work that goes into EFILive and look forward to a way of handling it in v8
