At present we can add messages from Admin--> General --> Messages and give path, which can be /topology, /cluster etc. It would be helpful if we can add message for a particular project. This would help in informing other team members about status of the project (for example: if the project is new; alerts can be ignored etc.).
Also, we cannot edit already created messages. If we want to modify message, we have to delete and retype the entire message. Please add ability to Edit messages.
