Support for Multiple Artwork Areas on a Single Surface

User Feedback
A user noted that the current setup excludes a wide range of print items and workflows where products have several print zones on the same side (e.g., front pocket + chest print, multi-panel designs, detailed packaging, promotional items, labels, etc.).

Requested Feature
Enable support for multiple artwork/image placements on the same product surface, each with independent smart-object mapping, positioning, and rendering.
