The ability to trigger an orchestration based on events (i.e., a change in a table) is set so that a change in any of the listed tables triggers the orchestration. In other words, the condition works as "OR" rather than "AND". However, some use-cases may require the "AND" condition. So, I suggest allowing for it.
Note - an event-based trigger is not a property of an orchestration (meaning that it is not a part of the file/folder structure compared to time-based triggers. So, I suggest associating rules with the orchestration.
Thank you for your consideration!
