1. What version of Thingworx are you currently running? 9.2.3 foundation and flow
2. Describe the problem you are trying to solve. Please include detailed documentation such as screenshots, images or video. When creating a trigger for a flow, you can select the product context you want it to run in. However, you cannot select multiple contexts nor select to run at the ORG or site level (to cover off multiple contexts for one trigger). Instead you have to copy and create multiple flows with multiple triggers. this can get out of hand if you have many contexts that you want a flow to run in.
3. What business value would your suggestion represent for your organization? It would allow single source of truth for custom flows, and not have to administer duplicates. It will allow more streamlined and understandable flows.
