iOS Email App - Saving multiple attachments

I’m looking for an iOS email app that can do something that seems simple but I can’t figure out a way to do it:

“Save all of the attachments to a specific Dropbox folder”

Every month I have a meeting, and the email for this meeting has about 10 attachments to it. I want to save them all, but don’t want to do it one at a time.

Is there an app that can do that, or is there a way to do that which I’m overlooking?

(For the moment I’m using SendToDropbox.com and then using VNC to my Mac to manage files. Which isn’t very efficient, but it’s more efficient to the 1,000 taps it would take on iOS.)

I know if you’re using Office365, Flow can be used to save attachements automatically to a folder. Alternatively IFTTT can save gmail attachements to a folder.
