Looking for Tools to Auto-Generate Product Proposals for Manufacturing Clients Using HubSpot

Hey guys - looking for tool suggestions - please don't DM me Our client has 200-500 products with photos, item numbers, item names, and collections. They are a retail manufacturer. We use HubSpot. We want to be able to choose a category or product type, and auto-generate a proposal with those products in it to send to a prospect. I am very familiar with PandaDoc and Portant but was wondering if anyone with manufacturing / design experience has used another tool they recommend? Right now, we have a large flipbook with <100 products and images, but we want to filter those and send specific ones in one flipbook to a client without having to manually change the document each time.
