Fundraising on WP Multisite - Predefined configuration

I am using the Fundraising plugin in a multisite environment.

I want to be able to set the configuration for each site, and then the user of that site, not be able to change it.

This is used for a user to create a page, and then use it to fundraise for the same charity (paypal email address). The user of the page can create their own "Fundraiser" but it all needs to go back to the same email address which will be pre-defined.

I am hoping that I can configure everything, and then use a cloning plugin so that each new site is created with predefined settings. However I am not sure how this will work with Paypal's IPN configuration.
