Will there be an update to have Sign Artist work on the signs provided in some of the new apartments?

Came here to ask the same:

So the console error for this is: 

[Sign Artist] Couldn't find the required image size for assets/content/structures/rentable_shops/signs_paintable/rentable_shop_sign_d.prefab, please report this in the plugin's thread.

Add them to the ImageSizePerAsset Dictionary down in the Init() method. I spotted 6 variants looking at a stringpool file. I have no idea if they are all used, and I don't know how to get the correct sizes. Maybe you guys can figure that part out. Use `lookingat` command to check sign names, and adjust ImageSizes as these are just a guess.

//Apartments rentable shops
["rentable_shop_sign_a"] = new ImageSize(512, 128),
["rentable_shop_sign_b"] = new ImageSize(256, 128),
["rentable_shop_sign_c"] = new ImageSize(256, 256),
["rentable_shop_sign_d"] = new ImageSize(512, 256),
["rentable_shop_sign_e"] = new ImageSize(128, 256),
["rentable_shop_sign_f"] = new ImageSize(128, 128),
