Is there a way to load some tileset for all (or selected) objects at once to for Sprytile Paint tool?

[kkolyan]

I have a level created by a common Blender tools and going to texture it with Sprytile Paint tool. There are a lot of objects on scene and I cannot find a way to load some shared tileset for all (or at least for selected) objects.

Example:

1. Create a house (exterior only) consisting of roof, door and walls. Roof, door and walls are different objects.
2. Select all 3 objects
3. click "load TileSet" in Sprytile menu and select picture
4. select a roof - new material is seen in material editor
5. switch to edit mode - TileSet popup is shown
6. switch to object mode, select a door - no materials in material editor
7. switch to edit mode - no TileSet popup

Is it supported?

PS: I use 2.82 fork, but this functionality looks very general, so I decided to post question here.
