Can you create dynamic pipelines or have a pipeline execute a pipeline? If I get a list of items from a service, and I then want to run each item in the list through it' own pipeline, ideally naming the pipeline to the item name, what is the best way to do that? I am currently using a single pipeline and a composite solid, calling that solid for each item in the list. Disadvantage to that is the pipeline then has a solid for each record and visually in DAGIT doesn't look great. It would be good to have them disassociated in a sense, where one pipelines instantiates a series of pipelines for each list item, then those pipelines get scheduled to execute.
