5.2 Beta 2 - Passage list(s) created when adding clippings

I am not sure whether this is a bug or a feature...

When I add a clipping to a clippings document, a passage list is created containing any Bible references in the clipped text.

If I then add another clipping to the same clippings document, a second passage list is created containing the Bible references from the newly clipped text.

Suppose I add ten clippings to the same document.  I now have 10 passage lists.  Unfortunately, I have no need for any of those passage lists.  So either I leave them to clutter my documents, or I have to delete them all.

If this is a feature, I would prefer if it were optional, since I don't need the passage lists.

Also, if this truly is designed behavior, would it be possible to combine the lists so that one passage list is created for each clippings document rather than one passage list for each individual clipping?  At least then I would have fewer unnecessary passage lists hanging around waiting to be deleted!

Thanks...
