Create multiple placeholders for different type domains

Can I have different placeholders for different domains?

What I need to do is have a for sale sign on some of my domains, instead of the normal placeholder.

Is there a way to do this?
I guess if I create a reseller account, and be able to have a seperate default place holder for each reseller, I can easily do this, but I don't know how and if possible.

How about creating a parked domin? Would that help with my problem?
