In one of Robert's recent videos analysing a PC motherboard, he showed the way the parallel traces of the busses were routed as a series of shallow upwards and then downward zig-zags, so that they weren't aligned with the direction of the internal weave of the FR4's glass fibres, and thereby maintained good impedance matching for all the bus traces.

What I want to know is how you would implement this in Altium Designer, as the routing styles seem to me to be either locked to 45/90 degrees, or they are "any angle", which means there is no defined routing angle, and therefore no way to get a complete bus routed with the same neat set of matching up and down angles.
I also have a secondary reason for wanting to be able to select (say) 30-degrees for the routing angle, rather than just a choice between 45 and 90.
I do a lot of boards that are hexagonal, or that have repeated circuit elements placed with rotational symmetry, and the ability to match the routing angle with the angle at which the components have been placed on the PCB would be very helpful.
We can specify an arbitrary angle in the preferences for when rotating existing objects, so why are we limited to 45/90 whilst routing tracks and busses?
Or have I simply missed where the relevant option setting is located?
