I'm new to Vector Style Editor. I created a style based on the Light Grey ESRI style. I am happy wiht it excpet its missing Roadway shields. I have another style that does include the shield I want. I am not understanding how to bring those over into my new style. I assume I have to edit the json, which is fine, but I also need to upload the sprites and I don't see a great way to do that. I am abel to add one sprite at a time, but I see no way to upload a family of sprites for different text lengths. So when I reuse the json, it doesn't see the sprites organized in the expected way and I guess fails to use it? Is there a way to downlaod and upload a whole sprite sheet for a style? Or at elast a way to upload a family of sprites?
