Allow user to define the number of recent files in Report Designer

The Sage Report Designer splash screen features a section called Recent Files, which shows the last 5 reports which have been run by the user, I run 10 reports on a regular basis which means I have to keep on going back to the menu to run them. Therefore I would like a user option to be able to specify how many reports are shown under &Recent Files& this would save me a lot of time.
