Concur is not an internally created product; rather, SAP acquired it. As a result, the technological platforms are distinct and not accessible via SAP GUI. Concur does provide APIs, but an internal developer or IT professional could only use them if your company paid for access.
Concur does provide a service known as an Image Delivery Extract that would send extracted expense reports or invoices together with their associated receipt photos via your business's sFTP site. However, end users cannot use IDE or sFTP since they are managed by the firm administration. To my understanding, the procedure you're presently employing would be required for someone who wanted to download their own photographs.
It's probable that this isn't something that is done frequently because there is a question of a similar nature in the community that has no helpful replies. (https://community.concur.com/t5/Concur-Expense/Does-anyone-know-how-to-download-expense-receipts-via...)
I apologize for not being able to be of more assistance, but I do hope that the explanation is at least somewhat useful.
