Interchangeable Vials

Sometimes life happens and you have to leave your active, in-use vial at home and take a pen with you instead. I’d like to be able to have the option to choose which vial I’m using (in other words, the ability to have more than 1 active vial at a time while keeping tracking features for each vial) before logging my dose so I don’t have to completely discard my current active vial at home and ‘start a new vial’ each time I plan to use a pen or a different source. Thanks for the improvements so far though!
