Use of SHIFT key to Select Groups of Channels

[jguarrasi]

I would love for there to be a way to select or de-select groups of channels in the channel list using the SHIFT key (Click a channel, hold SHIFT while clicking the channel at the end of the group).  In order to avoid getting a "Failed: A socket operation was attempted to an unreachable host" error on some channels that I make recordings on, I have to regularly re-do my channel scan (usually every 2 weeks to be safe).  Perhaps my cable co routinely changes things, I don't know why I have to do it, but I do.  Anyway, there is a block of about 100 music channels that I have to de-select by clicking one at a time...  Very tedious.  Having he SHIFT selection option available, would make this process much easier.  Thanks.
