You might be more comfortable starting with a non-facing page document. That way, you could set your bleed for all four sides without having to split facing spreads.

The bleed setting could automatically cut any crossovers…
If you stop the bleed where it crosses the spine, it isn't a bleed any longer, and you can already do that. You can also use facing pages and increase the width of your page to include a bleed area at the spine and make crop marks in the bleed area instead of using automatic crops.
