Is it possible to create workbenches in FME Cloud or Server that would allow users to drop in two excel spreadsheets to perform a simple but customizable feature merger?

I am constantly getting asked to perform extremely simple excel tasks for my co-workers - vlookups, pivot tables, etc. Is it possible to create a workbench where they could just drag and drop their two spreadsheets, select their requestors and suppliers and hit run? I know how to do this in FME Desktop but how can I recreate this on cloud with a super simple user-interface and save myself some time?
