Changing tablespaces on IMP?

Is it possible to change the tablespaces of the tables during an
import, from their original ones? Right now when we import a schema
from our clients, to bring the data down to out test servers, we have
to watch the error messages from the tablespace not existing, create
the tablespaces, and then try again.

Oracle 9.2i, 10g v 1 and 2. Windows, Sun, Linux.

Thanks
