knime birt node

I have passed 4 tables as data set to data to report BIRT node and created a report layout. This output layout is stored in the knime workspace.

Is there any option/ solution where i can create a flow variable for different output path and pass that flow variable to BIRT node and bind it to save the report to that destination path. Or After binding, can we take that same output flow variable to some other node to store Data to report birt file output in the specified path
