How to change the fundraising directory template?

Yes, I have read fundraising-templates.txt but it seems like it does not cover the directory template.
The directory template has a sidebar which can not be influenced by me. Normally Plugins use the standard template but this seems not the case here. So I can not address the sidebar / widget area.
I am using the intent pro theme.

Can you give the a taxonomy, so I can create a custom template in my theme for the "fundraising directory" page?
