As discussed in Files overview, references are internal links within Workpapers to existing files to reduce file duplication. References are automatically created when referencing files on the worksheet/other schedules entries, as shown in Adding & referencing files on a worksheet; however, references can also be manually created in-bulk.
Steps to Bulk-reference files
Accessing Files
Navigate to the files tab in the app or use the embedded file tab on the worksheet screen.
Select the desired file from the folder.
Creating References
Click on "More Actions" and then on the "New References" button.
Name the references and navigate through the breadcrumb tree to select the relevant accounts and schedules.
Select the locations for creating references and see the count update as you make selections.
Finalising References
Once satisfied with the selections, click on "Create References" to complete the process.
It's as simple as that!
