ID input for merge by distance node (geometry nodes)

I think the merge by distance node should have an ID input to allow intersecting geometry to merge itself by ID instead of making multiple selections and repeating merge nodes. This will make workflow easier and keep geometry node trees simpler reducing lag in large node trees.

(The "connected" setting on the merge by distance node does not connect geometry that is linked, only by geometry that is directly connected.)

(repeat nodes does not fix this since it cannot change a selection by its iteration)

In this demonstration I wanted to merge the vertices together for each individual cylinder but keep each one separate so I used multiple merge by distance nodes and compared the index for each piece. this can become impractical for large meshes with lots of pieces and is very slow to adapt to.
