Can we exclude hashtags in a hashtag column?

**Is your feature request related to a problem? Please describe.**
I'd like to see #generativeart, but many people are using stable diffusion and calling it generative art. I don't want to see AI art.

**Describe the solution you'd like**
I want a column for #generativeart but exclude a post if it's tagged #aiart or #stablediffusion. I can do that in the default Mastodon UI because it has separate "any of these", "all of these" and "none of these" fields. I don't see a way to do it in Phanpy.

**Describe alternatives you've considered**
I tried using a search `#generativeart #typography -#aiart -#stablediffusion`, but that wasn't giving me a timeline view, it was pulling from way in the past based on relevance.

**Additional context**
BTW, I love that you are creating new ideas for the UI! So many people just make a Twitter clone and call it a day. The boost carousel is fabulous!
