[otrs] Setting Title / Subject through mail filter

Hi, Simple question, maybe asked and answered before, but can not find it: We would like to set (alter) the ticket Title / Subject through a mail filter. Where the text should be retrieved from the mail body. But from SysConfig an X-OTRS-Subject or X-OTRS-Title does not exist. How can we realise something like this: Filter Condition Header 1 – Body - .*Description: (.*) Header 2 – From – EMAILADDRESS: somebody@somewhere.netmailto:somebody@somewhere.net Header 3 – Subject - .* has some fixed text .* Set Email Headers Header 1 – X-OTRS-Subject – [***] Except X-OTRS-Subject is not an option in version 3.1.3 Somebody maybe has realised in another way? Kind regards, Frans Stekelenburg
