CREATE TYPE and %ROWTYPE

(Sorry if this appears twice - I sent the previous mail as the wrong mail ID)

PostgreSQL 7.4.5

Is there a way of using %ROWTYPE in custom types?
I want to return two/three complete record areas to a calling 4gl program.
I can define a custom type, ie:
CREATE TYPE myTest AS (
fld1      INTEGER,
fld2      VARCHAR,
fld3       .......etc
);
This works fine. But if I define:
CREATE TYPE myTest AS (
area1              tableName1%ROWTYPE,
area2              tableName2%ROWTYPE
);
I get an error. This then means that I have to define myTest with the individual fields (which I can do) - but which in turn means that if the tables change, I have to remember to change the procs.
