Creating Multiple Variables Output are time consuming and not efficient when we need to send different multiple values for each pipeline execution.

I want to be able to generate a JSON object for consumption by and API also later in the stages/steps.

Lets say I have 20 values I need to export in my pipeline, now I need to define every value in my output step and then. If I could instead generate a JSON object that vas defined as "JsonVariable" and then later in the pipeline (or API) it can collect the data needed during this step. If I create a JSON variable right now as a string, it contains the escaped characters, and when I call this from the API I need to clean up the escaped characters.
