How to keep array NAVALUE of Measure constant?

Hi,

I register a measure "A" with navalue "-1". Running a mace expression on measure "A" changes the array navalue to different value other than "-1".

Here, i can use syncNAValue on the measure and i can change the array navalue of the measure back to "-1".

Is there any other way to prevent the measure's array navalue from flipping? like any parameters/configuration tools/rules to avoid this flipping on the particular measure rather than using syncnavalue utility?

Thanks
