Aggregation sum for all keys within field

[Hammad_Ali_Khan]

Hi there,
Just curious if there is a better way for aggregation sum for a structure like this
{
"combiner_energy" : {
"INV1-CB1-kWh" : 121.15685325833331,

}}
rather than I define all key for aggregation is there a way something like this
"aggs": {
"NAME": {
"sum": {"field": "combiner_box.*"}
}
}
