Custom Field Automation based on Project/Task Name

I would love to have an automation rule so that anytime I create a project with XYZ in the Project Name Field, it could automatically add data to Custom Fields. 

For example, when creating a project pertaining to photography for a Living Room vs Dining Room, we'd use LR or DR in the project title. Later in the process, I go through and select the custom field option for the category pertaining to that text.

Has anyone found a workaround way to do this using blueprints perhaps?

Thanks in advance!
