Restore imposible

        Hello, gurus

        I am practicing some hard restore scenarios. I got to the following 
unsolvable (for me) case:
        This is on Windows. Backup is made on RAC database stored on 
ASM. Restore has to be done on simple database on simple file system. The 
database is in archivelog. No catalog database is used.
        The catch is, that AFTER the last backup, a new tablespace is created 
(undo3). I cannot use SET NEWNAME for it's file because it does not exist 
before I reach it with RECOVER. The RECOVER command cannot create it because it 
tries for ASM. Here's the script so far:

RMAN> run {
set newname for datafile '+DGINKASO/inkaso/datafile/system.259.614014161' to 
set newname ...
restore database;
switch datafile all;
-- No problems so far
RMAN> recover database until sequence 50 thread 1;

starting media recovery
archive log filename=C:\ARCHIVE\ARC00019_0614014506.002 thread=2 sequence=19
archive log filename=C:\ARCHIVE\ARC00016_0614014506.001 thread=1 sequence=16
archive log filename=C:\ARCHIVE\ARC00017_0614014506.001 thread=1 sequence=17
creating datafile fno=6 name=+DGINKASO/inkaso/datafile/undo3.272.614107635

ORA-15001: diskgroup "DGINKASO" does not exist or is not mounted
ORA-15077: could not locate ASM instance serving a required diskgroup
ORA-29701: unable to connect to Cluster Manager

        The question is: is there any way to change datafile name/location 
during RECOVER?
