Your other question is regarding relative paths and how they are resolved on processing a TRDX file. All relative paths are resolved based on the start application, where if the service is hosted in separate project, the start location is the service project's execution folder.
To manually route relative paths, you can use the suggested approach - to append a string parameter to the relative path in an expression, where the parameters value points the base path to the resource.
