Modifying Name of XML E-Mail Attachment

Hey all

I need to know how I can change the name of the xml-attachment using the submit function.

My current code looks as follows:

<event activity="click" name="event_click">

<submit format="xml" target="mailto:example@example.de?subject=test&body=text" textEncoding="UTF-8">

</event>

Currently the attached xml-file is automatically named “filename_Daten.xml”.

The goal is to generate the filename dynamically depending on certain values.

Thanks for helping me.
