I often found myself in the position when I needed to do something once, and then do something else repeatedly. So instead of using bool variables and having lots of variables that are used only once, I made a macro I called Half Gate:
You can recreate it if you often need this type of behavior. You can reset the macro whenever you want, and you can set the number of initial actions.
In your particular case, if you only need to perform the first and the second action once, a MultiGate may help you:
But if you need the first action once and the second multiple times, my marco will do the trick just fine.
