Preventing timesheets from being posted to closed periods

As a number of posts have indicated, the system does not prevent timesheets from being released into closed periods.

This is a big problem for many service business clients as they are frequently having to release timesheets that were entered late by the employee.  

It results in changes to the balances and reports in periods that are closed and this is a nightmare for accountants who discover that their bottom line figures have changed in opening balances.  It breaks one of the fundamental controls of an accounting system.

The “Custom Week” settings have an “Active” status but there appears to be no way to change the status to inactive.
