How to import Datamine strings into Leapfrog including a colour column?

It doesnt look like you can import datamine strings into Leapfrog as Polylines with colour codes attached to a column to distinguish them. We use this regularly at work to visualize Geology Underground lithology and structural contacts and model. Only way i seem to get them in, is by points. Would be nice if there was an attribute category to be able to import them as polylines with colour.
