AI Builder for A document with multiple Forms

Question

Using the power Automate AI Builder, there is a requirement to process a document (extract data) which has same form on multiple pages. Each page contains the same form from which data is to be extracted.

e.g. Page 1 there is a form which has 5 pieces of information that are to be extracted. Now for Page 2 again the same activity needs to be done.

e.g. it is a same form/invoice with a multipage document instead of individual document.

In such case, I have huge quantity of 500 or more such documents so separating to 500 different document is very difficult.

Please suggest a way to solve this issue.
