UI QoL Suggestion - Instance blocking "add" button at the top

Currently in filters and blocks, all the “Add instance/community/user” are at the bottom of the list. I have a large filter list requiring a lot of scrolling to reach the bottom.

Would it be possible to have this at the top instead?

Alternatively, when selecting a community to block (vis the … menu) is there a way to block the whole instance that community is hosted on? Primary use to block instances that are non-english.
