Allow us to reorganize title trees (for de jure drift, etc.)

I wish I could think of a better title for this, but here's the jist:

Let's say I have two empire titles. I want two kingdoms to belong to one empire and two other kingdoms to belong to the other. I want them organized as such so that in the imminent situation that the inheritance splits up, the resulting borders will be logical.

Let's say one of my vassals holds two kingdoms. One of those is inherited and one is a viceroyalty. I want to transfer a duke vassal to him. I want to give it to him specifically under one kingdom or another, so that in one case I don't have to bother with it later, or in another case I will get that duchy back.

Honestly, I would kill if transferring vassals was a simple as clicking and dragging them in the realm tree. It would make things a lot quicker, for me at least.
