I am not sure if this is allowed here, so please forgive me if references to external tools are not permitted and delete this thread in that case.
I built a small command line tool that maps Garmin Driving Range data from an R10 or R50 into a format the ShotPattern app can read. I use that app for course strategy because Garmin does not offer this feature, and I missed that option in my practice flow.
The tool helps you take your exported Garmin range sessions and prepare them for import. It saves you from manual edits and handles the club mapping for you. It is currently more suited for people with some technical experience, but if there is interest, I can look into turning it into a simple app that is easier to use.
If you want to try it go here:

The readme explains everything you need, so I cannot offer setup support for individual users.
If you want to try it, I am happy to share general info or hear your feedback.
