No need, it's easy to differentiate between large and medium sectors and if you want to get ppl close to the small sectors just say "get close to "x" wall/tower.
It's incredibly easy to add a numbered overlay- 2 for loops should be able to do it. Having it be an optional overlay, like the grid lines/shadows, would be kind of neat. Asking for swaps would be a little bit easier too. Not a big deal, but could be kind of a neat addition.
