There's no real reason that import/export buses have only a single filter slot as opposed to the 9 that the storage bus has by default. Same for formation plane filtering.

The UI should be harmonized, which has the side-effect of greatly increasing the default filter slot count to 9.

Any progress @dokastho?

I'll be taking up development on this issue, deliver by 04/14

Not yet, I'm working on #6833 still, it's taking me a little while to get familiar with the code base @ramidzkh
