Yes!

This is what I do (for solutions in homework assignments):

\definebuffer[solution][local=yes,nested=yes]

\startmode[solution]
\defineenumeration[solution][....fancy setup...]
\stopmode

Then, in the main tex file:

....
\startsolution
...
\stopsolution
....

By default, gives the version without solution. Compile with --mode=solution to get the version with solution. The same thing should work in your case by defining two modes: unabridged and translation. And then use --mode=unabridged,translate etc to get multiple modes.
