You can loop the region, or copy and paste the region in the track. By adding several cpoies of the initial region you can modify the settings and vary the pattern - make it softer or more complex, so that the track will not become boring.
Another thing you may want to experiment with is to select Show Arrangement Track then map out your song first with Intro, Verse, Chorus, Bridge etc. Then create the Drummer Track. It will follow your arrangement. Try it!
