My suggestion would be something like this:

"postConfig": [...], //renders to actual group: Other options
"additionalConfig": [{
//renders to a new group, in this case: Source
"name": "sourceUrl",
"label": "Source URL",
"group": "Source",
"type": "text"
}, {
//renders to a new group, in this case: Store
"name": "storeLocation",
"label": "Store Location",
"group": "Store",
"type": "text"
}]

or something like this:

"postConfig": [...], //renders to actual group: Other options
"additionalConfig": [{
//renders to a new group, in this case: Source
"label": "Source",
"icon": "link",
"fields": [{
"name": "sourceUrl",
"label": "Source URL",
"type": "text"
}]
}, {
//renders to a new group, in this case: Store
"label": "Store",
"icon": "market",
"fields": [{
"name": "storeLocation",
"label": "Store Location",
"type": "text"
}]
}]

Just to split some important template config, in order to don’t have a gigant “Other options” section, that’s my case right now, I’m splitting with separator type.
