It is more common practice to group circuits with tick marks, so instead of being GGHHHHNN it would be GHNGHHHN. Also the nomenclature of a comma between circuit numbers for some has a separate meaning. It would be really beneficial to have some ability to customize how the circuit numbers are displayed. As 1,3,5 could mean 1-3,5 or 1-3-5 or 1,3-5. Some companies use a / instead of a comma. There isnt one set standard, so some ability to customize the syntax is necessary.
