Rolling over content automatically from page to page
So while I'm great with many Adobe products (e.g. Photoshop, LightRoom, Premier), InDesign is still somewhat new to me.
My question is this: Is there an easy method for creating an InDesign document for a product catalog that allows content to easily roll over to the next page when new products are added?
The catalog I'm working with is essentially just a big, long list of items. As it stands right now (with the catalog file I was provided), a single new item near the top of the catalog would require me to re-arrange the content on 30+ pages. My goal is to recreate this entire catalog (or reformat it, if that's possible) so the tables and images automatically roll to the next page when they are added (just like a word document.)
I'm not sure how possible this is since my research so far has just included vague mentions to text anchors... I've not been able to make those work, and even if I could, I'm not sure if it's the best practice to use here. I'm hoping I'm ignorant of a really great solution, and that someone can point out a good way forward!
Thank you,
