I've added a custom post taxonomy called "Projects" and adjusted my theme to display extra information on posts that have projects associated with them (i.e. "learn more about this project" followed by relevant links).
An example of this can be seen here.
This works as intended on my site, but I want to also see the same behavior when the post is displayed using some other theme (like on my mobile site, or in my email subscriptions).
Is there some way that I can make this be default behavior for a post, regardless of theme?
