I also updated my VP version to the latest patch and I can confirm that this feature should be present:
@jck Could you please double check that if you open the Help tab and then click About that it mentions 20181030aj in the lower right corner?
Also: I seem to vaguely recall this feature not to appear on the very first time I right clicked on the lane, but I could be mistaken. Try to de-select the pool (or lane) by clicking on canvas somewhere (once) and then hover the mouse over the lane again and right click.
Hope this can help!
