Can I do 2+ database backup's in one RMAN session?

I want to backup multiple databases on one allocated "channel". Is this possible?

Example script:
CONNECT TARGET sys/pwd@DB1;
run {
allocate channel t1 type 'sbt_tape';
backup database format '/oracle/backup/DB1/%u';
}
CONNECT TARGET sys/pwd@DB2;
run {
backup database format '/oracle/backup/DB2/%u';
release channel t1;
}
exit;
