Question about: "id": "#c:is_forest",

Is it possible to use this code for better structure generation ?

{
 "values": [
   "#minecraft:has_structure/village_plains",
   "#minecraft:is_jungle",
   "#minecraft:is_forest",
   "#minecraft:is_mountain",
   {
     "id": "#c:is_forest",
     "required": false
   },
   {
     "id": "#c:is_jungle",
     "required": false
   },
   {
     "id": "#c:is_mountain",
     "required": false
