Shared Spreadsheet Multiple Tabs

[blarp1]

Posted a speadsheet with multiple tabs. In a shared mode the sheet always defaults to the first tab. The tabs are consecutive weeks. (4-10, 11-17, 18-24 etc.) I would like each user to have the spreadsheet default to the current week tab. Is this normal for a shared sheet to default to the first tab, not the last saved tab? If it is the norm is there a way to force the spreadsheet to a different tab? Thanks
