Yes that is primarily what the generic "Awana" club name is used for .... to have a generic club name that you can assign leaders to.
There is nothing wrong with assigning leaders to a specific club, especially if they are say the Sparks Director for example, but you will always have some leaders that serve multiple clubs (pastor, commander, secretary, games director, and any folks who serve on a floating basis wherever they're needed), and it is these leaders that are most appropriately assigned to the "Awana" club.
Another approach to keep it simple and consistent is to just assign ALL leaders to the "Awana" club and then use the Leadership Role to identify the relevant club such as: Cubbies Director, Sparks Director, etc.
