If you need to upload a specific page range to Dalim instead of the entire PDF, there currently isn't a way to do this using Connector.

Instead, use InDesign's PDF export dialog box to create a PDF and then upload the PDF. 

To Export a PDF using Page Ranges:

Select the radio button for Pages: Range and enter the pages you want to Export in the Range field, separating them by commas (e.g., 1, 3), or using a hyphen to Export consecutive page ranges, or using a mix of both (e.g., 1-5, 7).
