[Lazarus] LazReport feature request

[Giuliano Colla]

When you invoke the ShowReport or ShowPreparedReport methods of a 
TfrReport, you get a preview of the report, with a "Save Report" button.

Save Report will open a file dialog, which defaults to the user home 
directory, and an empty Filename.

Dealing with inexperienced users, I would need to set the DefaultDir and 
Filename of the file dialog to something meaningful by the application 
point of view.

Is that already possible, setting some TfrReport properties I've been 
unable to find, or it would be necessary to patch LazReport by providing 
additional public properties, or providing overloaded versions of 
ShowReport and ShowPreparedReport, with additional parameters?

Thanks for any hint.
