Changing fundraising template

I understand I can create a specific template page for the Fundraising plugin, but why is the template for the panel itself buried in a the template_functions.php file? It would be better if it was a content template or at the very least something I could just drop into my child theme.

It looks like at the end of the template_functions.php file, it says I can overwrite the function in my theme, but I get an error that the function has already been declared. Is there any documentation for this plugin outside of https://premium.wpmudev.org/project/fundraising/#usage? This is just a page describing the plugin capabilities.
