Is nested aggregation possible with FT.AGGREGATE?

Hello

I chose Redis over Elastisearch for my projet and wondered if we can do nested aggregation like ES ?
My use case is pretty simple I store geolocated Posts in Redis and they have an attribute “category”, and a geohash attribute

I would like to aggregate by geohash/ and by category
In ES the result would be something like that

“aggregations”: {
“byGeoHash”: {
“buckets”: [
{
“key”: “ut09ung”,
“doc_count”: 12,
“byCategory”: {
“buckets”: [
{
“key”: “bar”,
“doc_count”: 5
},
{
“key”: “restaurant”,
“doc_count”: 12
}
]
}
},
{
“key”: “ut09unu”,
“doc_count”: 1,
“byCategory”: {
“buckets”: [
{
“key”: “bar”,
“doc_count”: 1
}
]
}
}
]
}
}
