You can record the Klopfgeist click but maybe you prefer to make your own. Just put some MIDI notes in a region and trigger a software instrument of your choice. Or use a loop that grooves a bit, depending on the type of music. The steady mechanical click is not always the best. Then, preferably, record a couple of measures to an audio track and duplicate them there.
If you have tempo changes and a fixed arrangement, you can make an instrument click for the whole piece and record it to an audio track. I don't know exactly why, but I always prefer an audio click. It is easy to make, you just send the instrument to a bus and on an audio track you record from this bus.
