Any tool to combine Apple Watch heart rate + indoor bike distance into a virtual GPX for Strava?

When I do indoor rides with my Apple Watch, I get time + HR but no distance. If I add a manual ride on Strava, I can enter distance but then I lose HR data.

Is there any app that lets me: • input my data of my spinning gym bike computer (for distance), • combine it with Apple Health heart-rate, • and generate a virtual GPX/TCX so it uploads to Strava as a normal ride?

Does this sound familiar to anyone else?
