Feature Requst: Auto up-voting only certain posts, but not everything from a user

Here's an idea. I really like SOME content from a user, but not all of it.

For example:

I love this post by @astromaniak:

https://steemit.com/bitcoin/@astromaniak/crypto-signals-november-events#@astromaniak/re-ashe-oro-re-astromaniak-crypto-signals-november-events-20171105t115838614z

But i don't really care about his other posts about Poland, etc.

Maybe I don't see every single "Crypto Signals" post, but I want to reward him for the work and organization because I find it valuable. I'd like to make sure I can auto-vote these posts, but not his other stuff. This way I show my support for the types of posts I want.

Would it be possible to create a bot that searches for specific tags or uses wildcards or regular expressions to catch and upvote posts in such a way?

In Liberty,
Ashe
