Hi Riya,
I don't know if there is a way to do it without creating a filter or object in the universe. Why don't you want to modify the Universe? If its a restriction issue to modify the Universe, then you should explain it better to people who're opposing it. Creating that filter or a Currentdate object in the Universe is one of the best practices, I'm sure many gurus agree with me.
How about updating the SQL generated by Universe? That sound's risky, isn't it? So, updating the Universe is the way to go.
Thanks,
Mahboob Mohammed
