Tile Names in Tileset Export

Help
1

I was wondering if there is a way to either name tiles, use their global index, or some other method to uniquely identify them in an export. The docs don’t indicate that there are any variables specific to tilesets for interpolation into the filename property of exports.

For example, when exporting a tileset using all the default values, one gets:

{
  "frames": [
    {
      "filename": "tileset.aseprite",
      // ...
    },
    {
      "filename": "tileset.aseprite",
      // ...
    },
    // etc.
  ],
  // ...
}

None of the other variables appear to differentiate tiles; is there any way to achieve this?

Thanks.
