JDT transform to modify N-th array element - json

Question

I am trying to apply a JDT transform to a JSON document in order to modify a property in a N-th array element. Is that possible without having to replace the entire element or even the entire array?
{
"array": [
{
name: "A",
value: 0
},
{
name: "B",
value: 3.14
}
]
}
Is there a transform that gets me to the following? I want to alter the 2nd array element and only its "value" property. I don't want to search for it by "name" but rather access by index.
{
"array": [
{
name: "A",
value: 0
},
{
name: "B",
value: 12345678
}
]
}

The challenge
It is easy to do your transform with some libraries in JSON. If your object is called foo, you mainly want to something like foo.array[1].value = "12345678" without any kind of looping.
The JDT way
I found How to use SlowCheetah to transform an array elements in Json config file? which asks
For example, if my base config file has this setting:
{
"Settings" : [1, 2, 3]
}
and I want to transfer it to:
{
"Settings" : [4, 5, 6]
}
The solution by Collin K was
{
"#jdt.replace": {
"#jdt.path": "$.Settings",
"#jdt.value": [4,5,6]
}
}
This seems like you need to actually replace the whole array.
Digging further let me to an open issue of JDT which seems to confirm this assumption.
Disclaimer
I have not used JDT myself, but I have been struggling with nested JSONs of various kinds e.g. with Elasticsearch.
