[Therion] Changing Atlas layout

Hello, i currently map a relatively long tunnel and want to be able to print it out on several A4 papers. The Atlas function of therion is the thing that solves this problem quite nicely. However, how can i tune the atlas layout, like disabling all visible features of the atlas (no navigation, no title, no borders when showing the overlapping (but the overlapping should persist!) The main goal is, to print the tunnel like it prints in normal export mode, but on several pages which break like it does in atlas mode.
