[galaxy-user] How To Keep Original Sample Names in Galaxy through Cufflinks pipeline?

Hello, Overall Problem: Given sample names are not carried through Cufflinks pipeline. Instead, they are referenced with a number and in final Cuffdiff output are referred to as Sample 1/Q1, Sample 2/Q2 etc., instead of given name which requires tedious re-labeling. Is there a way to implement -L function in Galaxy so that sample names are carried through from Cufflinks to Cuffdiff?
