Display modifer group name along with mo

We want to display modifier group names along with selected modifiers' names in invoice, customer display and kitchen display so that they can be differentiated easily. I am sharing a screenshot which shows a long list of modifiers from different groups but since the modifier group is not showing it is too confusing.I am also sharing a reference photograph which is showing is our exact requirement.

No body can recognize that which modifier belongs to which group. Sharing another pic of another pos which is showing modifers groups along with modifier
