From the Rewired documentation you should look at MapCategories. I copied only small section but I believe that is what you are looking for …

Map Categories
Map Categories are the first level of categorization of Controller Maps. Each Controller Map belongs to one Map Category and one Layout. The combination of the two serves to identify the Controller Map when selecting a Controller Map in the Rewired Editor or from the API.
Unlike Layouts, all types of controller maps share the same set of Map Categories.
Depending on your game’s design, you may choose to use Map Categories for a variety of purposes. One example use would be for a game that has multiple different game modes. In such a game, Map Categories can help you organize controls for your different game modes easier. For example, if you have the following categories each of which correspond to a different game mode: System, Menu, Gameplay Shared, Infantry, Vehicle, Airplane. This allows you to have different control mappings for each game mode. You can use the category to determine which maps should be enabled/disabled when you change your game mode, for example going to the menu screen or getting on/out of a vehicle.
