Being able to round-up by an interval in the reports is great, but I would also like to see an option to set a minimum value.
For example, we bill rounded-up to the nearest 15 minute increment, but have a minimum charge of 30 minutes. So, a time from 00:00:01 to 00:29:59 is billed as 30 minutes. A time of 00:30:01 will round up to 00:45:00 because the 30 min minimum has been met and we round up to the nearest 15 minutes.
I would like to see this option in the near future because I currently have to manually bump all my time entries under 15 minutes to just over 15 minutes so that the 15 minute round-up interval we have set will give us 30 minutes on that time entry.
