Is There any Feature in Cognos WSA to add customfolder in open report window box?

In WSA when we click on open option, choose window is prompted to choose a report, In that left panel we have Public Folder and My Folder Icon below that can we add a custom folder or tab created in CC below to those ICON's, If this is possible, please share the procedure with us, that  would help us a lot.
