Possible to make a v-cut on a single side, and spacing around the other three?

I have a board with castellated pins on the top and bottom, and a usb connector that sticks out the right hand side. I've had them produced before and the quick turn houses panelized it by putting a C shape around the left hand side of the board, with a vcut on the available mounting side, and spaces from the C to the castellated pins, with the usb connector just sticking out.

What I'd like to do with kikit is effectively the same thing:

• X mm spaces on top and bottom for castellated
• Y mm space on the right side for the usb connector that sticks out
• vcut on the left hand side (the only side without castellated pins or usb connector)

But I don't see a way to do this with the normal options, does it seem like this would require a custom script?
