Ignore proposed training when other activity is identified

I regularly do some other exercise in the provided available hours. For example in case of a group (social) ride or if I went running instead of cycling. I add this activity to Join and untick that it is according to the training plan. Subsequently I have to tell Join why I didn't do the planned training on that day (because I did a 3 hour group ride Jim).

Ideally this proposed training disappears when you already did a (substantial) exercise on the same day.
