Adding text for v-cut

One of our popular fabs adds text to callout the v-cut offsets.

Is this possible in the current KiKit?

While I don't think it is absolutely required, my general approach to these cheaper fabs is the more we can automate on our end, the less room there is for error on their end.

In this case both the lines and text are on the same layer "vcut".
