Mod #527 Block Invoice Sub-Totaling when Sorted by Temp Zone

Modify the behavior of System Option #67 - "Sort and sub-total invoice by Temperature Zone" so that the sub-totals are not printed. This modification includes an override to force the setting of System Option #67 to always be "Yes".

 

This modification accomplishes basically the same thing as Modification #106 but removes a separating line that was printing between items in different temperature zones.
