Can I somehow get past filling the report?

A police report Is part of company protocol to move forward with your claim. You cannot breach their policy by circumventing It.

Simply file one.

I'm also SE'ing another company which they might also ask for a police report, if they do, and I file the one for Walmart, can I use the same one for both companies?

No.

The report Is dedicated to the circumstances of the claim that It relates to.
