[Therion] Extended elevation and loops

Hi, I have a question to extended elevations and loops: In the attached file you can see a small loop in exteded elevation (ca8-ca17-ca9-ca8). Of course this loop is not closed (ca8-ca9 is open). But all shots have nearly the same direction. So I would rather like to show the loop closed and the shots not exactly in extended elevation. It is possible to display only the vertical extension of a shot (extend vertical xy). Would it be possible to display a shot in a specified direction of projection? For example: "extend 270 ca11" displays the shot ca10-ca11 in direction of 270 degree. This would allow to partly mix elevation and extended elevation. Would this be possible without too much work? Greetings, Paul
