I don't understand completely your question. Could you share it more detailed?
Is the problem related to only texts or data?
Are you need to show only the data on the latest order week?
Would you like to provide filter pane with every week orders, but your client have to be able to switch weeks?
I have only ever been able to save an applied filter unintentionally - so I know its possible, just don't know how!
Other than that hurdle, you could create a Dimension along the lines of:
IF(OrderWeek = WEEKSTART(TODAY()),'Current',OrderWeek)
then set your filter to 'Current'
when you next open it, it should recalculate the "current" week and filter accordingly.
