How to Enforce Approval on all Price & Discount List Revisions and changes?

Hi all,

We have a customer requirement where Price lists and Discount lists need approval every time there’s a change such as adding a new item, end-dating an existing price list entry, or creating a new price.
From what we can see, approvals are only standard during the initial Price List creation, and we haven’t found an out-of-the-box option for setting up approvals for changes or revisions afterwards.

Has anyone set up something similar, or found a good workaround or customization to handle approvals on every update to price and discount lists? Would really appreciate any insights, best practices, or examples from your experience.
