When updating/tracking a workout using the mobile app, we can include one-time exercises to the workout before saving it.

We are unable to do the same when updating a scheduled workout via the web. We can only add sets.

For example,

Let's say that during a session, I added a finisher at the end of the planned workout... if I need to input the data using the web, I would have to go into the training plan, edit the workout to include that finisher, then go back into the scheduled workout and put in the data. And now, that finisher will always be in that workout unless I remove it afterwards.

However, if I update/track using the mobile app, I can very easily "Add Exercise" at the bottom of the scheduled workout without affecting the pre-built workout in the training plan. Easy-peasy.

Please allow this flexibility in the webapp.
