feature request: pg_restore renaming target schema

Hi!

I need to restore one source schema to multiple target schema currently.
For example,

source database: db1
source schema: s1
target database: db2

The existing approach I know is following these steps:

(1) pg_dump -n s1 -Fc -f source.db db1
(2a) pg_restore -d db2 -n s1 source.db
(2b) psql -c "ALTER SCHEMA s1 RENAME TO t1" db2
(3a) pg_restore -d db2 -n s1 source.db
(3b) psql -c "ALTER SCHEMA s1 RENAME TO t2" db2

So far so good.
However, with existing tool I know, obviously step groups (2) and (3)
can only run sequentially.

If pg_restore allows "redirecting" source schema to target schema, then
I can concurrently issue some imaginary commands like these:

pg_restore -d db2 -n s1 --target-schema=t1 source.db
pg_restore -d db2 -n s1 --target-schema=t2 source.db
pg_restore -d db2 -n s1 --target-schema=t3 source.db

Best Regards,
CN
