Add custom paintings/ Signage for creative builds

I would like to suggest adding customizable paintings or decorative signs to Minecraft. Currently, banners and the existing paintings can be quite limited when creating detailed shops, malls, hotels, cities, and other realistic builds. It would be useful to have a system similar to the Loom where players could create simple custom designs, symbols, lettering, and logos on paintings or canvases. It could include different sizes such as 1×1, 1×2, 2×1 and 2×2, with selectable backgrounds, colours, letters and basic shapes. This would make signage much easier without requiring mods or complicated block constructions, especially for Creative Mode builders. I encountered this while building a luxury-inspired boutique and wanted to create a simple wall logo, but banners and existing paintings couldn't reproduce the design cleanly. I think customizable paintings would give builders much more freedom while still fitting naturally into Minecraft's existing building and decoration systems.
