Allow Edit on past shifts

Before the update, we were able to edit past shifts to cater for the changes.
With the update, we cant edit past shifts anymore. This is very inconvenient, as we cannot cater for sickies, or people that decide to leave early or come in late. our payroll is based on the shift recorded in roster elf, and this is starting to be super annoying because its a debate on every payroll. I started using RosterElf because it allows me to track time. Now it doesnt.
Please enable this feature again.

Else you will lose me as a client, and i will tell other people that you cant edit shifts, then this is not really a rostering app.
