PWD MKII Volume set

Is there a way to lock/set the volume at a certain level (higher than the pre-set 50) without turning it up every time when it is turned on? And if it is, can I lock it at 100? In another word, if I turn to 100, would it be ok, or it should be between 50 -100? The reason is I do not want to crank up my tube integrated amplifier if the PWD MK II is set at 50. Thank you in advance for your advice.

guess maybe just don’t turn its power switch off! it seems PWD will reboot & reset when power down, and on!

On the PWD on power up if the volume is above 50 it is set to 50. If it is below 50 it does not change.
