Does Azure Document Intelligence Support Multiple Documents Within a Single File?

Hello,

I'm working on a solution for a client where some of the documents contain multiple files within them. For example, a single file with multiple consecutive invoices on different pages. Does Azure Document Intelligence support this? Also, is there a way to tag files within a custom model so that the model can recognize different consecutive invoices?

I found out that creating a custom classification model might do the job, but as I have only one document type, it seems like overkill. Is there a simpler way to do this without training an additional classification model?

Thank you.
