Not in Standard Lojban. But one has been proposed for Academic Lojban:

Your example would be:

  koi'a xi i bu zmadu li no zo'au ro da poi [i in N]

It's not a pure afterthought system, in the sense that it doesn't avoid
all need to plan ahead, but even if a pure afterthought system were
possible it would be so complicated that it would be harder to use
than forethought (i.e. it would be easier to plan ahead than to
not plan ahead & have to go into contortions to undo the effects
of the failure to plan ahead).
