[Feature Request]: return filenames to result in pipeline

### What would you like to happen?

in text file output have
@Injection(name = "ADD_TO_RESULT")
can you make returning filenames to next step in pipelines?

### Issue Priority

Priority: 3

### Issue Component

Component: Pipelines

Start by tracing the text file output path and the `@Injection(name = "ADD_TO_RESULT")` entry point in the Pipelines component. Determine how pipeline results are passed between steps and define the filename representation expected by the next step. Done means text file output can return filenames into the pipeline result for downstream use, with coverage for the requested behavior.
