Timesheets generation beyond two periods

[#1]

Currently, timesheets are created for the current period and the next period. Can we have the option to create timesheets up to five periods. For example, we use weekly timesheet option. The system generates timesheets for current week and next week. This is fine most of the time, but sometimes people go on vacation for 4 or 5 weeks straight. It would be great if they would have the ability to enter the timesheets for the 4 or 5 weeks before they go on vacation.

...and for people on leave - it would be great if we could generate x number of timesheets for a specific person.
