Is there a way to do what would be an ALTER SYNONYM?

I've got a synonym created that rotates between pointing to two different tables. Sometimes it points to TABLE_A, sometimes to TABLE_B. (This is so that behind the scenes, I can truncate and reload TABLE_A, and then swap, etc. so the table "never disappears".)

However, when I want to switch the SYNONYM from pointing to TABLE_A to pointing to TABLE_B, the only way is to:

drop synonym table_syn;
create synonym table_syn for table_b;

Is there a way to make that instantaneous for the database? If someone does a select at the exact instant between those two commands, it'll error out, because the table "won't exist".
