Start a rule in a rule

Thx Tom for your quick reaction!
But for example I use this Progressive Dimmer rule as a wake up dimmer.

But I have changed/added some things (the dimLevel to 90 instead of 100).
I have made another rule to do the same when I trigger a switch.
But now I would rather have de dimLevel to 70 so I have to change it twice.
Is there a way to make a “standard rule” to dim the lights and refer to it in another rule?

to be clear I want this part as the standard rule

if (timer === null) {
    timer = createTimer(now.plusSeconds(0), [ |   //Starts immediately
        Light1_Dimmer.sendCommand(dimLevel)
        if (dimLevel == 100) {
            timer = null // cancel timer
        } else {
            dimLevel = dimLevel + 1
            timer.reschedule(now.plusMillis(timeoutMills)) // reschedule timer is 3 * 600 mills
        }
    ])
}
