If Thunderbird is set to prompt for a destination when saving attachments, it prompts for each file separately when saving multiple attachments at the same time, unlike how it is in Outlook with a similar option to prompt for save location: it only prompts 1 time and uses that location for all of the attachments you're attempting to save, rather than prompt for each of the files. The reason for asking if there is a way to change this behavior is that if you are saving hundreds of files from an email, being prompted hundreds of times instead of just being able to make a choice once would save quite a lot of time. To clarify, the behavior I'm asking for DOES exist in Thunderbird when using the "Save All" button but, if you are not using that, and are instead selecting specific multiple attachments (not necessarily ALL) from the email, the behavior I described above is what happens.
