At this time it is not possible as ProCalV5 does not house the information, only a link to the information. In your example the "Linked File" is pointing to an address that requires an internet connection and possibly networked passwords. It would be more likely to make this available for Document files such as Word, Excel, PDFs...
Thanks for the Feature Request. This is something challenging for now based on current architecture but could evolve depending on how much the ProCalV5 application and related systems will have access to the linked file paths you are using and how much bandwidth your download can allow.
I've documented this as a Feature Request in our system, reference number 05799
Would like to be able to export SOP documents (Document ID) associated with PMs export query to ProcalV5 Mobile.
