Each month, our organization has dozens of journal entries that are imported for payroll and other month-end close items. Importing these entries is great as they spread across multiple funds. However, after importing, it's a pain to attach the same file dozens of times for documentation purposes. It would be extremely helpful if there was a button on the "list" journal entry screen (the one that shows all pending or approved entries) to attach a singular file to all selected entries.

I think this could work similarly to the "Post all" feature available so you don't need to post each entry one by one. You could upload/drop a file and then attach it to all related journal entries so you don't need to attach the same file one by one.
