Better control of Series Recordings

When you set a show to series recordings, you are asked if you want All episodes or only New ones. Where is the option to record New episodes but only on a particular channel, usually the current Main one.  Many shows are shown on multiple channels now due to syndication, so you currently get New ones on all channels.  But the New ones on some channels are many years old, but "New" on that channel. So, for example, you currently get CBS but also channels like ION, UPtv, etc where I only want the new current CBS ones.
