I never tried before today, but it seems to work just fine:

parallel -S localhost --trc {.}  'mkdir {.}; cp {}  {.}/abc{}' ::: a.b c.d e.f
parallel -S localhost --trc a{.}  'mkdir a{.}; cp {}  a{.}/abc{}' :::
a.b c.d e.f
parallel -S localhost --trc {.}  'mkdir {.}; cp {}  {.}/abc{}' ::: a.1 a.2 a.3

The last will complain that the dir 'a' already exists, but will work fine.
