${NUM} in the output cannot be reset back to 0

Hi,

I added ${NUM} to the output file naming convention.

${NUM}_${capturetime:d"yyyy-MM-dd HH_mm_ss"}-${title}

However i could not reset it back to 0 even if i exit the program and restart it.

Can you advise if there is a way to reset this number back to 0?

Regards,

Peter
