Ah! sorry about that, there is another way but it gives too linear a path and you'd still have to adjust manually.

I can't remember what it's called now and I'm in work so can't check but it goes something like this, You do a copy and paste of the tree and then I think you either use the * or the # with CTRL on the keyboard and a dialog box comes up asking how many you would like to do and it does them that way but it's very linear so you'd still need hand adjusting but it might work.
Can't think of another way right now!
