Request Type: General Addition

Try to describe all workarounds and associated issues that make it necessary to add this block in your eyes.
Request to add 3 new Utility blocks: "Residential" "Workshop" and "Shop"
They would be used in OT and future large town/cities plotting.
They would fit in the meta data of the current Utility blocks set (iirc 2158, using 2158:10 2158:11 and 2158:12), so no new ID used.
