Expose old row through the emitter #13931

Closed PClmnt closed 2 weeks ago

PClmnt commented 2 weeks ago

Description

As part of some of the work going on to allow users to trigger automations based on specific parts of a row that are updating, we want to expose the old row both through the event emitter (for use in further work) as well exposing the binding directly within the bindings drawer.

Launchcontrol

Exposes a binding that allows the user to see the previous row whenever using an Update Row trigger. Allowing comparison of the previous and new rows in subsequent steps.
