In LifeCycle Designer 4, when sending a file (i.e. Submit by e-mail) on a pdf form, the name of the pdf seems to be random - is there any way of giving it a name e.g. New Form.pdf

I think that I got it  with the name in the Submit e-mail button.  However, I would really like to add the date & time automatically to this file name - is this even possible?  Otherwise each pdf file has the same name and when saved it would have be renamed or it would overwrite the previous one.
