Redirect To Weekly Time Tracking Form

How can I redirect to the Weekly Time Tracking form instead of the default Time Track form?  The following code snippet works fine and takes me to the Time Tracking form……

recordCreated = nlapiCreateRecord('timebill');
recordCreated.setFieldValue('employee', name2);
recordCreated.setFieldValue('location', '5');
recordCreated.setFieldValue('hours', '0');
recordCreated.setFieldValue('item', '77');
recordCreated.setFieldValue('payrollitem', '2');
recordCreated.setFieldValue('customer', instructorid);
recordCreated.setFieldValue('trandate', trandate1);  
tranum = nlapiSubmitRecord(recordCreated, true);
nlapiSetRedirectURL('RECORD', 'timebill', tranum, true);

….but I want to go to the Weekly Time Tracking form instead.

Any way to do that?

Thanks;
Frank
