[Solution] How to make a subclip...

Can anyone tell me, why I can't select a clip on the timeline and drag it to the mediapool to make a new sub clip or what you will call it...
And when I have the "sub clip", I would like scene detection so I can grade every time there is a cut...
Right now it just takes and makes a FULL timeline!
