Hey @Stuart Weenig, in 186 we’re adding one toggle that will allow you to save all alert settings for a module, including, no data, trigger/clear interval, message, subject, description, and the actual threshold values and operator.
We do eventually want to have all fields be preservable at some granularity, as well as clear indicators of which side made the change. Ideally, we’ll pre-select the most obvious settings for you (preserve all your customizations, update all un-customized fields, make the user adjudicate conflicts, where both LM and the user have changed the same field).
