Limit “Assigned Posts” dropdown to specific pages

Hi, I’m using the “Review: Assigned Posts” field in a custom review form and I’ve set it to show Post Type: Pages.

On the frontend, the dropdown displays all pages on my site, but I only want users to be able to select from a specific subset of pages (for example, only certain product/service pages).

Is there a way to limit or filter the Assigned Posts field to only include specific pages?

Basically, I’d like to have a single review form on a master page where users can choose which product/page they want to review, instead of having to go to each individual page to submit a review.
