Dynamic layout/output format depending on parameter possible?

Hi Gurus,

We are to extend an EXISTING BIP(RTF template and using XML Data Template as the data definition) report. Current report output format is in PDF.

Now user wanting additional parameter value to determine the data to be fetched and the OUTPUT FORMAT.

Existing Report: If Parameter1 = A  then

Result:

1. Existing query fetch

2. Output format is PDF

NEW required addition: If Parameter1 = B then

Expected Result:

1. New query fetch(different multiple columns from existing) to be added in the current xml data template

2. Output format should be in Excel(or csv)

Question:

Is it possible to do the above required by updating the existing RTF + xml Data Template report?
