Is it possible to set up a template to use on a single based on a query variable?
Example: I have a custom post_type called vinyl_records and use add_rewrite_rule and query_vars filter to support the following permalinks.
vinyl_records/spinal-tap/appraisal which sets the query_var appraisal=1
I want to use a specific themer single layout when the query var is present and equal to 1? Is this possible?
