Bind rain gages to subcatchments spatially, in one undoable step.

Two methods:

Proximity — assign the gage whose Thiessen (Voronoi) cell covers the largest share of the subcatchment's area. Uses the real watershed boundary rather than a representative point, which matters as soon as a subcatchment is large relative to the gage spacing.

Interpolated — area-average natural-neighbour weights over the gage network for each subcatchment, group subcatchments whose weight vectors agree, and materialise each group as a generated gage backed by a generated series. SWMM binds exactly one gage per subcatchment, so an interpolated field cannot be expressed any other way.

Everything is computed before any mutation: the volume-conservation gate can therefore abort with nothing written. The whole assignment is one undo macro.

Complements the per-object gage field in the Properties panel and the attribute table — those set one subcatchment at a time.
