InDesign Export to Interactive PDF: Always exports spreads?

I noticed that there is no checkbox for “Spreads”in the Export to Interactive PDF dialog box out of InDesign CS5. The export is always in spreads and you can’t turn it off. Personally, I wish this dialog box had a few more options (some permissions settings perhaps?)

This seems kind of lame. A quick fix is to change your document setup so it doesn’t have facing pages, and then to turn it back on again after.
