Custom Cleaning Options

It would be great to include the following items in Custon Cleaning Options. (I know thay can be done via winapp2 but that looks kind of technical so the entry via the buttons in custom clean would be easier)

As of now there is option to add a folder which deletes all the contents of a particular folder like for eg

C:\WINDOWS\Temp\*.*

1) Similar to this a registry term can be added to delete all the entries inside a key like for eg

HKEY_CURRENT_USER\Software\Sonic\RecordNow\Preference\MRUImages\*

(It shouldn't delete the whole "MRUImages" key itself but delete all the stuff inside it)

2) In add files an option can be included to add like for eg

*.chk or ~.*
