Use arbitrary repetition/shift length

I received feedback that the repetition feature is confusing and nearly useless when needing to create shifts which are not 1 hour long. I imagine one of these two approaches could make sense:

either

• repeat n shifts, always using the end time of the previous as start time of the next shift ("i want 4 shifts, each 2.5h long starting from 20:00 in the evening for my bar")
• or repeat n shifts, using a customizable offset instead of just selecting hourly/daily/weekly ("i want 4 shifts, each with a start time of x hours/minutes after the first start time")
