Invoice Email Replies

If I copy and paste into the attachments section on the invoice so that I can attach to a reply, it names them the same. Then when I go to reply and attach, all it list is the name, no way for me to differentiate the two. Needs a better system, either by making attachments unique names and naming them accordingly, or the reply window needs a thumbnail. I think unique attachment names would be a better fix, then it could fix this issue on tickets as well since sometimes the attachments may be similar and it’s hard to tell which one is being attached.
