Lists are not interchangeable between Insert and Dual routing mode. You must recreate them for each.
It would be awesome though if those lists were available in either mode to see at least. So you could load and then edit them. Or even better, convert them directly. Then you would only need to adjust the inserts when in insert mode or adjust the algorithm to the preferred path when in dual mode. All hot switches, parameters, etc. could stay the same. Or am I mistaken?
