Randomising Script

I've had an idea that with the testplan area of the wiki it would be useful if we could randomise the apps that are listed in the testplan.

Example test might look something like this

Include UbuntuDesktopWhole
Include Gedit
Include F-Spot
Include fluffybunnies

Would it be possible to have something like this instead

Include UbuntuDesktopWhole
Includetests=3 UbuntuAppTests

So that 3 random tests are select from the collection of Ubuntu apps? And add a ## Start UbuntuAppTests and ##End UbuntuAppTests either end of the ubuntu apps in a similar manner to the testcases?
