Connecting Subgraph Input directly into Subgraph output without relying some custom node

### Feature Idea

Default Comfy Subgraph cannot connecting Subgraph Input into Subgraph Output directly (passthrough) without having some additional custom node. Using default Reroute node from Comfy Core make each Subgraph output unrecognizable. It would be great if we can passthrough directly to streamline the workflow.

### Existing Solutions

Using Pipe Edit node from tinyterraNodes ([https://github.com/TinyTerra/ComfyUI_tinyterraNodes](url)) help the Subgraph input (in this case the input is `model`, `clip`, and `vae`)passthrough directly into Subgraph output, and each ouput is recognizable.
