Due to the inaccuracy of swimming wrist photoelectric heart rate, I use a polar h10 to record my heart rate, is there any way I can merge the fit file recorded by the garmin watch with the fit file recorded by the h10, of course I would need to adjust the timeline of the heart rate so that the two moments are the same. Finally have the correct swim data and heart rate data files!
Try GOTOES.org
It might be able to what you want. You may need the premium version which iirc is a once of payment of about €10
Worth having a look. I’ve edited, merged etc. files before. It’s a great tool.

If you need a tool to merge or append in a flexible way, gotoes is a no-brainer.
It supports IQ fields and FIT export for a low one-off cost and is updated on regular bases.
I asked the dev to implement the Coros extra fields for running metrics and he got it done in a couple of weeks. Very responsive!
