Pro Site Plugin: Default Level for New Blogs

Hi,

I'm using the 'Pro Sites' plugin on my Multisite network, because I want to allow my users to have the 'Unfiltered HTML' option - if I want to apply this to every blog I create (it will be over 100), will I have to manually alter the site level to apply it, or is there a way to set a default level when I set up a new blog?

Hope this makes sense

Rob
