Rearrange iCal subscriptions

[Tiggar]

Hi there,

I am just wondering if the following is possible.

I have subscribed to various Google Calendars of friends, business colleagues and so on.
No I would like to rearrange these subscribed calendars and want to move them in a appropriate category of my own calendars. But iCal would not let me to do this?

Is there any known workaround to put calendar subscriptions in a same category with non-subscribed calendars?

Any help is appreciated,

Jan
