Is there a way to rename uploaded files within folders in Simpplr?

At launch, we uploaded all of the files that used to live in SharePoint, but many of the file names include version numbers, dates, etc. It's pretty ugly. In SharePoint we were able to just rename a file, but I can't find that option in Simpplr, and there are far too many to go through and re-download each one, rename it and reupload. Anyone experience this before? Any advice?
