I'd also be keen to see this. on occasions I've been out for a ride and stopped for coffee and have had the garmin autosave the ride before I get going again (I know, the stop was too long). I then have to start a new ride for the 2nd part and would like to be able to merge the two workouts into one in my TP calendar so all of the metrics are in one place.

For long endurance rides on Zwift, I often wind up with two or three workouts uploaded to Training Peaks, but only the first is posted to my Long Endurance workout card. It would be a nice improvement to be able to drag and drop the additional workouts to the workout card instead of having to download from Strava and then manually adding to the workout. It's the 21st century, right?

When using the new Strength Builder tool, I can enter the lift information via mobile app, but if I also record heart rate and other metrics via Garmin Connect, I end up with two cards on my calendar for the same activity.

The ability to merge cards would be very helpful in eliminating duplicate cards for the same event.

Add ability to merge two planned workouts cards together in Trainingpeaks.

I would make life easier if we were able to merge an activity recorded on multiple devices into a single activity. Currently I have to go into the duplicate activities and download each of them. Then upload them into the main activity. I do this because not all sources have all the data. With them combined I get to see everything in one view. Example is my ride on Zwift (for virtual distance and elevation), Wahoo Bold (dual sided power) and Garmin watch (backup).

Be able to merge activities through drag and drop like merging activity with a planned workout would make things much easier.

+1 for this. Especially for bike workouts, sometimes one can just do several of them in one go...
