Please add the option to turn off auto-fill of squads

I think this would be a HUGE QoL upgrade. In some game modes, especially raids for example, we may want to take in an undersized squad, and due to bad RNG, may need to make several attempts with an undersize squad. It gets very tedious when you go in for a retry, the system automatically fills the un-used spots in your squad, and with every attempt, you need to manually remove the unwanted toons. Please, please, please either add the option to turn off auto-fill, or just eliminate it completely (I cannot think of any situation where having the system auto-fill your squad with the next most powerful toons in your roster would be helpful). If I want to run an undersize squad, please just let me do it.
