Not yet. It's on their road map.

Hi Fillip, just sharing an answer as someone who picked up KWHero. There is currently no option to bulk upload keywords for research. You can bulk upload keywords into a content plan, but it doesn't do anything in there once you do that. If you run a content analysis on a single keyword, you burn 1 content analysis credit. The KWHero team seemed really keen on their webinar to beef up the keyword research component within the next few weeks, so not sure how that will look.
