Sending Files by Email via Contextual Menu

Morning.

If I send a file as an email attachment from DTPO via contextual menu I want Mail.app to use not the filename for subject of the email, but the subject (Betreff) given to the file in DTPO.

How can I achieve such a behaviour?

Thanks in advance and kind regards, Friedrich

What do you mean by the “subject given to the file”?

Also, you can’t do this without creating a script specifically for this purpose.
