I think the best thing is to ask for $10k or equivalent, and then let the HR team come up with a sane way to construct that value that works under their system. It's kind of like getting requirements where the customer tries to tell you the exact logic to program, but since it's not their codebase/background, they end up coming up with convoluted solutions.
Just tell me what you want, and let me as SME figure out how to get you there.
