I don't think there's an official way but you can try adding space characters to the end of your titles until they are basically left-aligned. If your set of fences is pretty much fixed, that should work okay.
I don't know if they are needed (I can't test anything at the moment) but if regular spaces don't work, non-breaking space characters should remain at the end. To make one, hold alt while pressing 0 then 1 then 6 then 0 again on the number keypad (not the number bar). You can also try copying the non-breaking spaces between the quotation marks below.
non-breaking space: " "
narrow non-breaking space: " "
