Create unique integer with ex_machina?

I am trying out ex_machina package – I do not see how to create unique integers however. Is this possible? My need is to simulate keys from foreign database. Thanks for advice!

@vrod if you want sequence of integer (as I needed today), you can use this, which will just return the integer value unmodified:

%{
   foreign_id: sequence("foreign_id", & &1)
}

There are probably better solutions, but I wonder if you could just use System.unique_integer/1?
