Add an Export Inspector option for something like "Execute pipeline"
It would be useful to have an option somewhere in the Export Inspector -> Data Extracts -> Writers drop down that only executes the pipeline up to your selected filter and doesn't register any writers.
An example is when you make a programmable filter that saves a matplotlib plot on apply, and you want to run that with a catalyst script in situ. To get that catalyst script, you still have to select a writer, either from the data extracts or image extracts, and comment it out later yourself. If you don't select an extract, you get the error:
Nothing to export, use Export Inspector to configure what you want to write.
