Projects OTL - Prior Periods Time Entry

 Hi,

I'm trying to find if there is a way I can change our OTL setup to allow users to go to earlier time entry periods than they can at the moment.

e.g.:

OTL / Create Timecard / Time Entry: 'Emp Name and No.' / Period: Drop Down List of available periods <-- this goes back 8 periods (weekly), I'd like further periods to be available.

I know that if no timecards have been entered at all you can select the oldest period, click on the drop down list again and 8 periods further back are available.  This can be repeated to go even further back.
