Construction bot range extenders

[BenSeidel]

I am trying to create a construction area range extender, a roboport that extends the range of JUST the construction bot construction area. The issue is that the connections between roboports are solely based on the logistics network range, so you cannot connect them without connecting the logistics network.

I have looked at reducing the logistics area to zero, but this prevents the roboport from connecting to anything if placed outside the existing logistics areas. I have looked at scripting the cell connections, but everything in the LuaLogisticsNetwork and LuaLogisticsCell are read-only. Likewise there seems to be no way of preventing cells from connecting to networks or creating two networks that overlap.

Does anyone have any suggestions or is this something that is impossible in the current build (0.14.20).

Thanks.
