The type of control you are describing is likely going to be achieved by a third-party controller or automation system (EasyTouch, Omnilogic, Aqualink), or potentially a simple controllable valve that is set to direct flow to the solar system during the same times you set the high speeds on the pump. If you use an automation system, the SmartFlo pump in can communicate with it using its interface adapter: https://www.discountsaltpool.com/CircuPool-SmartFlo-Interface-Kit_p_363.html.
