Custom role shows as an option for the site role but doesn't exist on new site

There is an option in the Site Role for the multisite options that includes the custom role I created in Multisite. I network enabled the Members plugin but that doesn't carry the customizations to new or existing roles to the subsite. If I choose a custom role, it creates the user on the new site with a role of none. Is there a way to carry this role to the subsite. I asked Justin Tadlock in the Members forum but he didn't know of a way to do it.

Any ideas?

Thanks,
Kiko
