It is possible to assign a tool preset to a specific layer. When the preset is selected, it will verify if the layer exists. If so, the layer will be selected and if not, it will be created.
When switching panels, by default Storyboard Prolooks for a layer with the same name as the one currently selected. If it does not exist, the first layer will be selected. To prevent Storyboard Pro from selecting a random layer, you can activate the Enable Brush Preset Layer Selection Lock option. This way, Storyboard Pro prevents you from drawing in the next panel unless you create the missing layer. Click on the preset again to create the missing layer.
