To save time of the users and skip redundant clicks, maybe an option for customizing can be developed for the below case.
When I have a document (e.g. Sales order) and it has linked documents in “Connections” tab, but for some document types there is exactly one linked document (e.g. Sales Invoice). When the user clicks the Sales Invoice, he/she has to see a list of one document and click on it in order to reach the target document.
So the question is “Is it possible to skip this list of one document and open directly the referenced document?”. The idea is if only one document is linked the user to land directly in the referenced document without going through the list of one document and to have to click on it.
