Does this addon have support for TileSets with more than 1 tile source?

I've been trying to paint some tiles from my second source in my Tileset and I cannot seem to get it to work. So is this a supported feature?

No. The idea of this addon is one AtlasSource per node. At least for now.
The easiest way to have multiple tilesets is to add multiple TileMapLayer3D nodes to the scene and each can have its own texture.
