Trending @Cognizant; Need to fill timesheet, having both project and bench days in same week.

Actually we need to submit timesheet for every Friday for the entire week. But here I'm having both the project days and bench days in same week. While filling timesheet the project ID option is available for one Project ID (couldn't update both the IDs like Project and PDP). Hence I'm unable to fill timesheet. Contacted my POC (timesheet approver) but she's not responding. I don't know what to do. Somebody please help me.
