Emailing form

Hi,  I would like to submit a PDF form created with Live cycle designer ES2,

I have set up the email creation & this is working well.  One issue is I would like to be able to rename the attachment (the form) to a value for the form itself, at the moment the form is attaching a copy of the default form.

I do not want to have to save the form as copy  “save As” as this reduces the point of the email submission.

Does anyone know a way to do this, it would be a great help.

Thanks
