Simple way to invert polarity of all links to and from a variable?

[kleemax]

When doing Group Model Building using CLDs, it often happens that the direction of a variable is inverted, e.g. from "helth" to "severity of desease" (or the other way around). This means that all Polarities of pre-existing links to and from this variable must be inverted. That's a lot of work in a workshop. Hence Is there a simple way to do this, ideally with one click? Could it be done in text-edit mode with some sort of find-and-replace in the sketch information (my guess is that's where the polarities are stored?)

It will need to be a manual process, there is no way to invert the polarities.

But it is relatively quick. Make sure the sketch is unlocked, select the arrows, then press either + or -. The polarity will be applied to all selected arrows.
