A wildcard for privilege assignment is not possible (think a bit more about it and you'll find that this would lead to very ugly situations - even without something like this the situation is messy enough).
You can either provide privileges on schema level or you defined it on table/view level.
For what you want to do I'd recommend to create a role and a script that grants the privileges for all the objects you like to see included to that role. That's easy-cheesy scripting.
You can even write a simple SQL that generates all the GRANT statements for you.
