Trade Chat Filter

Would it possible to set a trade chat filter so that only posts regarding things we are interested in come up? For instance, if I only want to buy an empower gem, then only the posts with the word "empower" in it will show up and the others will be muted? (much like the new search system for the stash, very helpful btw!)

Like that, we wouldn't need so many different channels, but just a set of filters.

I don't know how feasible this idea is, but it would make the trade chat a lot less spammy!
