Default [Q] Unistalling Apps From Phone NOT Marketplace

Hi guys, I'm hoping one of you can help me before I go mad. I am new to Android (I'm running the HTC Desire Android build on my HTC HD2) and I remember selecting an option (can't remember if it was in an application or the phone settings) that said Remove Application from Marketplace when unistalled (or words to that effect). Anyway, I buggered if I can find it again because I want to leave these apps in MyApps list. Can someone tell me where I can get to this setting

Many thanks in advance for any help guys
