With reference to https://answers.laserfiche.com/questions/50507/Is-there-a-way-to-get-the-Entry-IDs-of-documents-from-their-shortcuts#122734, I have the same desire for this column.
I would like to suggest that it would be extremely useful for Administrators to be able to have a column that would show the ID of the entry that any shortcuts would lead to.
We have implemented TRM and have a lot of automation creating shortcuts in folders for targeted records that we want access to in other folders. This automation often will create more shortcuts than we want, because the users have changed their minds about what they want to name the documents, sometimes tweaking the name two or three times (even though we do have a Naming Convention).
For example, one of our workflows creates shortcuts in a Project # folder whenever that Project # is entered in the Project # field. That way, all records relating to that project can be found in one folder, even though many of them are invoices saved in the Accounts Payable folders and some of them are agreements saved in the agreements folders, etc. Our users are being trained to name their documents first, then template... in order to minimize the number of shortcuts that get created, because every time they change the name of the document after templating, the workflow will create another shortcut. We have many of these scenarios.
If I had access to a column that could show me the ID of the entries these shortcuts are to, I would be able to see immediately which shortcuts I need to delete when I'm in a folder and notice that we might have extra shortcuts.
