Sadly, at this time there is no way to do this. It's either all of the recordings under the same grouping (series) or one at a time. This would however be a great suggestion to www.telus.com/ideas.
It would be better if the person(s) monitoring the Ideas page would monitor this forum also!!
Since they are connected, I'm sure they do. However, I try to recommend people to post there as well. The more something is mentioned, the better. : )
