Adding input_booleans and restart

I’m on HA 0.49.1. I am adding some input_booleans to change states in the house. After I add them, I restart HA to make them active. I know in the past releases some things like groups have been broken out and we can just use the reload groups button to bring those in without restarting the app. Can we do that with new entities like input_booleans yet? Also how about customizations? I forgot to expose it to alexa before I restarted just now…
