OSPF NSSA P-bit

Hello, guys!

I am reading RFC3101 about NSSAs in OSPF and trying to compare described requirements with IOS implementation. I am curios about P bit. As far as I know the nssa-only keyword in redistribution command allows us to clear P-bit leading to limitation of distributed routes to NSSA area only. But it seems that we can only clear P bit for all or nothing. So we can't regulate this P-bit granularly, right?

What if we need to clear P-bit only for a subset of redistributed routes? I couldn't find any set option in route-map. Is it possible?

Thank you!
