is there a way to add custom can channels. now that i am using a diy can-bus device, i have access to data specific to my car/model that isn't in the dropdown list. right now i plan on just putting the data in an unused field and remapping in race renderer. for example, in BMW ZF8 shift settings, S1, S2, S3. its not something i am logging continuously, but if i see a change, i output it.
