Consider that manual tagging is the simplest, least confusing, and most predictable option. It should therefore be the model for the primitive operation.

Now, of course, a tool that supports design automation should support "scripting" of shortcuts based on primitive objects and operations. Leaky heuristics may be acceptable as high-level operations if the user has solid primitives to fall back on. But attempting to use leaky heuristics as a foundation gives the user neither a conceptual foundation for understanding what the tool does, nor the capacity to override unwanted behavior. Especially when learning the tool, the user needs manual control over what's going on.
