I would like to suggest an enhancement to the system that allows users, particularly system administrators with the right privileges, to lock an entire week’s roster at once, instead of locking one shift at a time. Currently, this process is very time-consuming, and being able to lock the whole week’s roster would be a huge time saver. This feature would be especially important after invoicing and finalizing the roster to ensure that no one can modify the roster, which could potentially conflict with invoices already sent to customers.
