That is a very good question, unfortunately, it's not possible and we advise against it. What we learned is that large catalogs are less effective than multiple smaller catalogs organized by large categories.
For these reasons:
1. customers usually only look at the first pages and it's difficult for customers to find what they are looking for.
2. It's heavier (more difficult to send by email, takes more time to display in the browser, …). Basically, you convert more customers with multiple smaller catalogs than a large one.
