Import with categories?

When I use:

“Import posts to blog”

as the option for an RSS feed, is there anyway to maintain categories (tags) from that source?

Or do I need to manage this through automated tag categories via filters (like looking for a hashtag keyword or emoji)?

Currently you’d have to set up a filter for that. It’s a good idea to look at categories from the RSS feed. That’s something we could consider in the future.
