Fixed rhythmical pattern easily accesible for rapid notation?

One of the most widely used rhythmical patterns in songs, folk tunes, children's songs and even classical layouts is the "gallopp"- pattern concerning the syncopated eights, followed by a sixteenth (see picture below)
When you have a lot of this in a song it is rather tiresome having to construct each one of these figures separately. Could this be designated its own button, for easy reach when notating?
