I mailed support about it, and I think they are going to add it in a future version, but I thought of a way. You can go to settings and there is an option to only allow http/https urls to paste into the harvester url grid. Just make sure that is off and you can import all the proxies into the url grid - like import urls, but choose the proxy file, remove duplicates, save them off again and then load them in the proxy manager and test them.
