More control over geometry nodes

Hey small disclaimer I know this was discussed in some manner in the past but in 4.4 controlling built-in nodes in blender is still not fully available in a "procedural way".

For example, I'm creating a procedural sign with a "String to Curves" node. I want to control the font from outside in the modifier panel, but I cannot in a straightforward way. So here's my "design"/solution for the issue, I think it fits in the blender vision, maybe this doesn't got implemented because some code refactor is needed (no clue really).

Another example is to control the object by a string :)

It would benefit many other nodes like "capture attribute", "raycast", "sample index" and many many more! It would really be a gamechanger and make building complex nodes even more easy and convenient.

I really hope this goes noticed and be considered one day :)
