Modding Help Remove array element without knowing it's position in Rampaging Koala

Hello

This was the old way of updating a dile from original asset :

Code:

{
  "__merge" : [],
  "defaultBlueprints" : {
    "tier1" : {
      "__merge" : [ 
        "list", [
          [ "update", { "item" : "bandage" }, { "item" : "nanowrap" } ],
          [ "delete", { "item" : "torch" } ],
          [ "append", { "item" : "peanutbutter" } ],
          [ "prepend", { "item" : "timer" } ]
        ] 
      ] 
    }
  }
}

Actually with the new system, I know that we can do that :

Code:

[
  { "op" : "replace", "path" : "/defaultBlueprints/tier1/45", "value" : { "item" : "nanowrap" } }
  { "op" : "remove", "path" : "/defaultBlueprints/tier1/8" }
  { "op" : "add", "path" : "/defaultBlueprints/tier1/-", "value" : { "item" : "peanutbutter" } }
]

but if a mod remove the element 7, I would remove the wrong element so my patch would be easily incompatible with almost every mod.

so comparing to the old system, I can do corectly "append" but not "update", "delete", "prepend" directly by targeting the elements.
