No automatic opposite drawing layout available that I know of, but still could be... I guess I'm lucky enough to be able to add a note on the drawing saying; make one as shown and one opposite etc..
For me I have dropped the mirror to make opposite components, another one of those great dog and pony shows that you still need to have a work around, so I just model straight up, if I have a left hand, then I make a left hand part derived from the original right hand part... and mate that to the assembly it needs to go to.
Saving from making a new drawing for opposite hand items, you could make 2 "parts" or "Assemblies" on one drawing. It is an acceptable practice to have a call-out that states something like "View depicts opposite hand, See view [whatever] for dimensions, unless otherwise specified."
