Spacewalk clone-by-date channel and kickstart

I'm using Spacewalk 2.6 and successfully created base CentOS 6 and 7 channels and can kickstart off those. However, I recently created 6.8 and 7.2 cloned channels with the spacewalk-clone-by-date command, but cannot kickstart from those.

It seems that I may need to setup a kickstartable tree for those, but I'm not quite sure if that is correct, or how to go about doing that for a cloned channel?

Thanks ahead of time.
