Yes! You can do this on either a documents or proof approval report type. Below are snippets of the filter to use for proof decision status.
Document: Current Version > Proof Decision
Proof Approval (Option 1: Proof Decision is for proof as a whole): Document Version > Proof Decision
Proof Approval (Option 2: Proof Decision is based on one specific person's approval): Proof Approval > Approver Decision
Hope that helps, but let me know if you meant something different.
