On the ParseHub "Click" and "Go to Template" commands, you can select templates from outside of the project you're working on.
When using either of these commands you will find this option in two places:
1. On the "Click configuration" pop-up which appears when selecting either command.
2. When clicking on either command on the ParseHub sidebar.
To use this option:
1) Click on "Go to Another Project"
2) Select the project you would like to go to
3) Select the template you would like to go to on that project
