Is there a way that for events created on google calendar that repeat daily, take as the "estimated time" of the task, the duration of the event (start time and deadline)?

If a event created on google calendar, start at 11:00hs and end at 13:00hs, maybe could program automatically the estimated time as "2 hours" (maybe the user choose on settings if wanna have this activated)

I know that i can program the estimated time myself, but i make that suggestion for the events of google calendar that repeat daily (or other repetition), because you can not program the estimated time for all the repetitions, just one by one, because are like single tasks.

PD: maybe this "automatic estimated time" could be for every task that have a start time and a deadline, would be so comfortable. (if the user want to having it activated on the settings)
