Add an exercise to an existing workout on the fly
In the previous version of the app, you could add an exercise on the fly. It helped when you simply added another exercise or substituted an exercise for some reason and wanted to record it accurately. i.e. maybe you substitute a DB bench press for a BB bench press. This can still be done on the browser, but is no longer available on the app. I resort to making a note in a notebook and entering it later when I am at my computer.

This is a very necessary and fundamental feature that should be put back in the app. I have clients that train at multiple facilities (ie traveling for business). The lack of this lost functionality has been troublesome for on the fly modifications. Trainers and clients need that on the spot flexibility option.
