Strenght Training - Add / Edit summarizedExerciseSets

[Acker537]

Hi,
the Garmin connect Strenght training realy sucks, so I had a dream....

1. I record my strenght training with a Garmin Fenix as a free training. So I get the puls data from my training into garmin connect.
2. I record and plan my strenght training with a second app. In the app I have the exercise name, sets, weight, repetion. I can export this information as CSV
3. I write a small program that reads the CSV and edits the training in garmin connect to add the exercises.

With "Get strength training exercise sets" I can download the strenght exercieses and the JSON also has the details in the "summarizedExerciseSets". But is there also a method to update/edit the activity?
