Multiple Input Nodes for Geometry Nodes Zones

Repeat, Simulation, For Each zones in Geometry Nodes are a powerful instrument and can lead to some really complex workflows and results. This complexity, however, gets in the way when it comes to keep the nodetree clean and tidy, by trying to get some simple values from one way to the other (deltatime in simulatioins is one obvious example).

The solution I propose, is to give the user the ability to insert multiple zone inputs for each zone. This would work by copy-pasting (or shift-d) existing zone inputs. This works already for nodegroups, so I suppose it could work for zones too, with some tweaks.

Visually, nodes inside a simulation are already kept together by the convex shape that forms around them. I understand that for some complex scenarios (nested zones, for example) that could not be enough, so some further design might be necessary but I think it's really worth the efforts, and would streamline a lot of work needed for a lot of cases.

Thank you for your great work :)
