Currently if you create a daily repeat schedule you have a 5 minute resolution but for a weekly repeat you have a 15 minutes resolution. Both the daily and weekly repeat align with the model start time and date, which is great!. So if you have a weekly repeat and you start your model on Sunday it will start with the schedule for the Sunday.
But if I want to start a break at 5 or 10 minutes past the hour and not 15 minutes on a weekly repeat I have to use the custom repeat option. But that option doesn't align with the model start time and date!! So I currently solved this filling in the table in the custom repeat option and then in the tree change the repeat variable to the weekly repeat but if you by accident open the timetable your table is screwed up again.
So my solution would be that the table for drag and drop your times has a user defined resolution so that you can define the times per 5 minutes or even per minute.
