Heya Stuey... Not sure if you were able to resolve this but just wanted to jump in with some thoughts, just in case
Just an FYI, if you're not already aware: if you do not apply any segments or are not using custom reports, you should not get sampling overall.
hmmm you can set up rollup reporting and in the roll up, you will see all the inquires from the filtered views in your main view but then you would have the filtered view, so you can get better percision.
Does that get at your question? If not, if you have any other details on what you're looking to do, I'd be happy to provide further clarification!
