I get what you mean now. Unfortunately not at the moment. Each pattern has a priority, and the one with the highest priority wins. Two patterns can be running at the same time, for example if your tablet is fully charged and you get an email - when you dismiss the email pattern the battery-full pattern will still be displayed. Some other people did also suggest something along these lines in a thread/brainstorm suggestion, but I think it would take a rewrite of mce to get it working.
