Nothing currently - basically to get ensured continuity you have to use either Blends or Fillet, often Fillet can be easier though.

It can be better to build things that come to a sharp distinct crease between the surfaces which then tends to fillet better, filleting can have problems if the surfaces are already partially continuous or nearly so, because it makes for either a tiny fillet strip or one that is collapses down to nothing along a range of the fillet.
