When ‘Estimate for Me (US)’ is selected, add an option to display and/or copy all assumptions which exist under the hood to a ‘custom’ settings view. As an example, I live in a part of NY state where there is no local income tax, it would be great if I could still leverage the estimates which are otherwise applicable, while tweaking the local income tax line item from (what appears to be ~1.49%) to 0.

This could provide a more general solution to a number of the other more specific tax related suggestions, and be more intuitive to users who don’t wish to seek out a public roadmap/discord server for workarounds.
