Edit all aspects of time entry

In order for the Syncro PSA to be of any use, my staff and I need to be able to edit all fields of a time entry, including the start date/time. I can’t fathom how this is not already possible. The fact that, in order to fix a common mistake, I have to completely recreate an entry, is not only a waste of time, but makes this product appear very unpolished and flimsy.
