Hi! This is actually already possible with the plugin's existing layer control commands.

One simple approach would be:

1. Create your normal tree layer (for example, Green_Tree).
2. Duplicate that layer and replace the image with a snowy version (for example, Snow_Tree).
3. Keep the snowy layer hidden by default.
4. When your Winter switch turns ON, use the Control Map Layer plugin command to show the snowy layer and optionally hide the normal one.

Example:

Control Map Layer
Layer Name = Snow_Tree
Action = Show
Permanent = true

And:

Control Map Layer
Layer Name = Green_Tree
Action = Hide
Permanent = true

Then simply run those commands from an event page conditioned by your Winter switch.

The same method could be used for seasons, destroyed/repaired buildings, day/night decorations, story progression changes, and similar map variations.

So while there isn't a dedicated "asset switch" feature that automatically swaps images based on a switch, the current layer control system already allows you to achieve the same result quite easily.
