IMPort Utility sucks

I've using Oracle for several years now, These last two days, I've been battling with the IMPort utility: Is there any way to tell it not to use the "storage" clause that it has, and use the default instead?
I'm trying to rebuild a test database out of a production one (a big one), and I do not have all the space that it needs. So I keep getting the 1547 error message

Any help would be very much welcomed
