I have discovered that you can override this by client.  In Screen 17.1, Click on the "Carryovers/Misc Info" selection in the middle left hand pane.  The last line of the first section (just before Form 4797 input) is Print all assets on Form 8949: 1=yes, 2=no [O].  Enter 2 here and the entries will move to lines 1a and 8a.
