Merged node UI: Renaming a merged node input or output does not have an effect on the labels in the subgraph view

[NonLogicalDev]

Renaming a merged node input or output does not have an effect on the labels in the subgraph view.

To reproduce:

• Create two nodes (for example two Vector / Add)
• Select both
• Click Merge Selected Nodes
• Enter Subgraph
• Try renaming Inputs / Output from Import Index N to something else (Like Dimention)

Expected:

The names change in the UI

Actual:

The names stay as Import Index N

Examples:

View outside the subgraph after rename:

View inside the subgraph after rename:

Added reproduction steps.

It also does not seem to be possible to constrain the node input/output types like the built-in subgraphs (like Artboard).

For example constraining them to vector or color values.
