Thank You, MarioD,

I tried it and that method works! It is one keystroke more than dragging into Cubase, which can receive the drag directly, but still quite good. I can't seem to use it to drag multiple tracks (can you?) I suppose if there are a lot of tracks it may be quicker to use the Wav function in the upper right and export all the tracks (without mixdown) and then drag all at once from the folder into Studio One, which works to receive multiple drags from a folder.

(So, being able to use Studio One with BIAB I think the program is finally good enough to switch from Cubase. Although it is missing a few things that Cubase can do, there are plenty of other things that it does more efficiently.)
