How can i edit the autosave tag <title>?

Hi there!! i'm a newbie in the forum, so i claim the wise and knowledge of the gods of this forum to solve this....

The problem is the following:

I use a program to create reports that makes them out with a "." ( and when i print this with the autosave options it comes out with like this one: ""

When i send this by email, some e-mail servers detect  this as an attempt to change the real extension file... no comments here

The question is that is there any posibility to edit or change the tag so i can "trim" the title o erase everything after the "dot"?

I know it would be simple to change the title of the file, but it becomes a real waste of time by the 300th title change...

Thanks a lot for the help!!!
