Is it possible to write in custom PIDs for logging bits/bytes from the canbus stream? Like say I knew what canID I wanted to look at, and the specific bits of the canID. And I knew what it was and how to scale to useful information. Will the logging software do this?

Essentially, is there a .cax option for the logger? I understand we can modify available pids and such, but can we add in something that is otherwise not currently offered but I know exists on the transmitted GMLAN stream?
