Analysis for Office Excel file - Changing back-end BEx query

I have Analysts for Office Excel file that used BEx Query to fetch the data form SAP BW. Is it possible to replace BEx query used and embedded in the file with another BEx query while preserving every other setting? For those who are familiar with WEBI - I am wondering if there is 'Data Access' -> 'Tools' -> 'Change Source' feature for Analysis for Office.
