Sending document version by email, remove date/time from filename extention

Hi,
sending docs version by email works, but, the file extension is “poluted” with the date/time…

So the problem: when I try to open the file, as windows doesn t recognize the file extension I have to manualy select “open with… adobepdf”…

is there a way to remove this “date/time” from the filename sent by email ?
