No warning message before overwriting of attachments in 1Password.com accounts

Today I found out the hard way that you can overwrite an existing attachment (or Document if you prefer) in 1Password.com without a warning message.
I added a software license item with an attachment and then clicked "Edit" on that attachment. After that, I uploaded a different attachment. I had expected that it would add this attachment to the existing Document or at least warn me that this action would overwrite the original attachment.
I could restore via Item History, so no severe damage was done. But I still think it would be a good idea to have a warning message telling you about that behaviour.
