I think you may have to redo the Grid System or the numbering of the individual Grid Elements because it only intelligently numbers them at placement. Later they become individual Grid Elements and cannot renumber themselves if any of them is removed or a new one is added.
That would be a great feature but currently the Grid System is basically a tool for the initial placment many Grid Elements in one step along with Dimensions/Beam/Columns etc. as needed.
I guess we could say that it is a good idea to know exactly how you want your Grids before placing them so you can avoid additional work.
