In trying to build a list with planar geometry grouped by its x location; such that geometry at the 12th station appears at the 12th index in the list, I am boxed into another corner I cant get out of.
If there is less goemetry than stations, the list needs be padded with nulls before and/or between and/or after the geometry.
If i start with a list of NULLS and use REPLACE, i get NULLs in the branches with the geometry.
If just create a list with the correct indexs for the geometry, it seems I cant add NULLs at the other stations (one per station) as placeholders if you like
