Custom "Recent Comments" block

Hi Beng,

Is there a way to have two "recent comments" blocks that display contextually? Here's what I mean:  say I have a "blue" channel and a "red" channel.  When viewing stories on the blue channel, could I get only comments posted on stories in the blue channel to show up in the recent comments block? As it stands, the "recent comments" block shows comments across the entire site ("blue" and "red" channels). In other words, is it possible to have only comments on stories in only one channel show up when viewing stories in the same channel?

Your help is greatly appreciated as always.
