editing remote files from Pycharm ?

I read answers from 2011 about the lack of support for editing remote files in PyCharm
I wonder if anything has changed since:  In my situation the code is located on a remote server which I can access through ssh - I am not allowed to manually copy the files locally (for security  reasons)
instead of editing it using emacs or vi I want to use PyCharm (or intellij with python plugin)
I was hoping that maybe you have any support for this (maybe in the professional edition)
possibly with a local cache directory under the hood that will be kept encrypted in some way
Do you have such a solution ?
