Custom Houzz Icon

Site is in development and I cannot link you to the page. I have linked to a screenshot.

I am using custom icons, but in the setup/admin page I don’t get the option to add a custom icon for Houzz.

Here is a screenshot showing that the other custom icons work:

I need to be able to upload a custom icon for Houzz.

Thanks!
