Cannot use multiple URL sources for a single HTTP Texture Tile Layer.

Describe the solution you'd like

Ability to use multiple URL sources on a single HTTP Texture Tile Layer.

Describe alternatives you've considered

Alternatively, instead of using multiple URL sources, ability to use another replacement string {s} which refers to available server codes.

//Input via inspector
string[] serverCodes = new string[3] { "a","b","c" };

//URL source
https://{s}.tile.server.com/{z}/{x}/{y}.png

//Results
https://a.tile.server.com/6/36/24.png
https://b.tile.server.com/6/36/24.png
https://c.tile.server.com/6/36/24.png

Additional context

Possible conflict:

• Treating a,b,c as different textures on cache systems

Possible feature:

• Adaptive server(s) selection based on download speeds
