Camps and Class Manager currently doesn't support session specific documents in confirmation emails. As a workaround, you may use the Conditional Display Text widget to inert a hyperlink of different documents.
Please follow the steps below to insert different documents for different sessions in your confirmation email:
  1. Setup Conditional Display Text Area When Customizing Confirmation Email
  2. Under the Confirmation Email page, drag and drop Document links widget in your email content
  3. Click on Select Files
  4. Click on Upload new file to upload all of the documents for different sessions
  5. After the documents are uploaded, hover your mouse on the document name, right click on the document name, select Copy link address
  6. Repeat Step 5 to obtain the hyperlinks of different documents
  7. Paste corresponding links into the corresponding text widget of different sessions
  8. Remove the empty Document links widget in Step 2 from your email content as it's for obtaining hyperlinks only
