Every layout has to be edited one by one, I'd love to be able to just make a new layout and for it to already have my alerts added, because it always starts with the predetermined ones.
You can do this by linking your alert layer. Then in each scene, when you click Add Layer, you can add this linked alert layer and its settings will be preserved from the other scene in which it was created. A linked layer allows you to seamlessly make edits to your alerts layer across all scenes from any scene. Linked layers share all properties except their position, so you can adjust the linked alert layer to best suit the current scene you're editing without affecting its placement in other scenes; however you won't need to edit every other aspect of it (such as color, image, etc). Hope that helps.
I would like to have the option to add the same alert box for all layouts; at the moment I have to add the box to each new layout I create, and if I start customize it, i have to change it for all layouts.
Instead I would love to have an option to have a centralized alert box that I can add to all layouts as default, and any edits I do will be applied automatically to all
