I have several blogs and write about varying topics. Is it possible to use tags or categories to segment the topics to specific blogs?

For example, when I write about National Podcast Post Month in November, could I use the hashtag #NaPodPoMo to indicate to HiveWP that a particular post should go to https://napodpomo.org? Then when I write about the #WalkTalkChallenge, it would go to https://walktalkchallenge.com, etc?
