You can do it manually in the tile editor or you can run this bit of code every time you load a tile map:

For element (value) of (array of all(The tile you want) locations):  
Set wall at (value)

You can find the “for element” block in the loops tab.  
Hope this helps!

I have coded this roughly a million times ^

Here’s the code:

> Made with ❤️ in Microsoft MakeCode Arcade.

I’ve also finally opened a PR to add this to the tile util extension:

> Adds a single block to this extension that lets you set walls on/off for all tiles with a given image. I have coded this roughly a million times on stream and we also have people asking for it on the forum:
