Select Short Curves

Is there any way to modify the behaviour of SelShortCrv so that window select or lasso-type selection can be used to select the curves? I’ve just imported a view made by Make2D in another model and as usual it’s festooned with thousands of the little critters, but I don’t want to chance deleting what may be useful short curves in the rest of the current model.

In the meantime, I can only think of temporarily exporting the Make2D output to its own file and using SelShortCrv in that contained environment.

Lock or hide other geometry before running short selection?
