Elite Drivo - Can I turn off Erg Mode when using Garmin WO?

[Steve Rode]

When doing intervals using my Garmin bike computer (1040) I prefer to set resistance or grade then shift to a gear that get's my cadence where I want for the interval. I find that during ramp up at the start of an interval the trainer adjusts sometimes faster than I want, same when I am fading on an interval and I can't hold the target power. I can adjust the power target on the Garmin or set it to in grade or resistance for just that one block and it will return to erg and the new target power as soon as the workout proceeds to the next step. I would rather not have to keep using the head unit at each step to go back to resistance / grade mode but if I don't the resistance can ramp up and basically bring me to a stop and it's nearly impossible to get going again.
