Great idea!

I've put together this script which serves as a workaround for "Printmaster Mode" for the Track Control Deck:

const trackName = {
    track1: "Track 1",
    track2: "Track 2",
    track3: "Track 3",
    track4: "Track 4",
    trackPM: "PM",
}
const trackArmed = "track punch enabled and armed"

function armPrintMaster() {
    sf.ui.proTools.trackGetByName({ name: trackName.trackPM }).track.buttons.whoseTitle.is("Track Record Enable").first.elementClick();
}

function printMasterMode() {
    
    const track1 = sf.ui.proTools.trackGetByName({ name: trackName.track1 }).track.buttons.whoseTitle.is("Track Record Enable").first.invalidate().value.value
    const track2 = sf.ui.proTools.trackGetByName({ name: trackName.track2 }).track.buttons.whoseTitle.is("Track Record Enable").first.invalidate().value.value
    const track3 = sf.ui.proTools.trackGetByName({ name: trackName.track3 }).track.buttons.whoseTitle.is("Track Record Enable").first.invalidate().value.value
    const track4 = sf.ui.proTools.trackGetByName({ name: trackName.track4 }).track.buttons.whoseTitle.is("Track Record Enable").first.invalidate().value.value
    const trackPM = sf.ui.proTools.trackGetByName({ name: trackName.trackPM }).track.buttons.whoseTitle.is("Track Record Enable").first.invalidate().value.value

    //Checks for record arm state and arms Printmaster accordingly
    if (trackPM !== trackArmed && (track1 == trackArmed || track2 == trackArmed || track3 == trackArmed || track4 == trackArmed)) {
        armPrintMaster()
    } else if (track1 !== trackArmed && track2 !== trackArmed && track3 !== trackArmed && track4 !== trackArmed && trackPM == trackArmed) {
        armPrintMaster()
    }
}

function loop(action, interval = 250, timeout = 5000, name = "PrintMaster") {
    var now = (new Date).valueOf();
    if (now - globalState[name] < timeout) throw 0; //Exit if we were invoked again inside the timeout
    globalState[name] = now;
    sf.engine.runInBackground(function () {
        try {
            while (true) {
                sf.engine.checkForCancellation();
                action()
                sf.wait({ intervalMs: interval, executionMode: 'Background' });
            }
        } finally {
            globalState[name] = null;
        }
    });
}

loop(printMasterMode)
