Tool unclamp / air pulse/ clamp logic without ATC carousel

So I have a pneumatic atc spindle, with 4 pneumatic functions (unclamp, clamp, air blast and seal cleaning air(always on when machine runs)) and some sensors. But I don´t have an ATC carousel yet.

This means I have to load the tools manually, via the Tool tab, and by actuating some pneumatic valves by hand in order to get the tool to be released.
If I enable the ATC tab, I can also use the clamp / unclamp buttons (not sure yet if these are directly triggering the m64 P# or calling the subroutine. If subroutine, I could add logic over there)

What is the recommended way to manually load tools in Probe Basic?

Is there some dialog or button I can use to call the subroutine for clamping, airpulse and unclamping which I´m overlooking?
Or is the expectation that this is handled via a hardwired button, as long as no ATC is used?

Hard wired button. If you add an ATC you would use a motion.digital pin in the ATC stubs to activate, but you would still need the manual button for hand the spindle to store in the carousel.
