Time Entry mask

First, great app (MacOS) minor request w.r.t. data entry. When entering the timestamp, input has to be of the format HH:MM (colon seperated) to display in the listing. If possible can the input routine automask/determine if colon is present in the entry, if not either populate before a PUT call is made? Probably easier then altering the display routine to fill the display with the ‘:’.
For example if I enter “1123” - the UI displays as ‘1123’
enter: “11:23” → ‘11:23’.

Looking at this from the perspective of rapid entry (sure it’s just 1 character) but it’s a SHIFT-; and on phone/tablet - even more or a pain.

Thanks for the consideration.
