Manual introduction

It would be a good idea, that we can introduce sessions manually. For instance, I go to practice with a teacher and don't use this app, but I would like to have the total time I practice. You could divide from the total the time with the app, and others... Sorry about my bad English. Thank you.

Hi, we have a feature on iOS "Add missing practice session" - this doesn't exist on Android yet. But basically it allows you to manually add sessions later. Is this what you meant/want?
