Option for AND-combined filter rules + author specificity

[awebeer256]

Pitch

I want to be able to create a filter that matches all posts by X user, that contain ALL (instead of any) of a list of filter keywords.

Motivation

I follow the EFF. The EFF has a podcast called, "How to Fix the Internet." Every time a new podcast episode comes out, they make a post to shout it out.

But my podcast player already automatically downloads and queues up new episodes of this podcast, so those posts are wasted space to me. I want to filter them out, but still see the EFF's other posts. To minimize false-positives, I would need a filter whose logic goes like this:

author: @eff@mastodon.social
AND substring: “How to Fix the Internet
AND substring: https://www.eff.org/deeplinks/
AND substring: /podcast-episode-

But I believe the only supported type of filter currently is this:

substring: foo
OR substring: bar
OR substring: baz
OR ...

I'm sure I'm far from the only person who is subscribed to a podcast and also follows a fedi account that always posts about each new episode of said podcast in between various other posts.
