Lenses that show number of cities within 6 tiles and 9 tiles

[FaerunPlayer]

I would like a lens that showed the number of cities within your civilization that are within 6 tiles
Another lens that showed the number of cities within 9 tiles (for when you are suzerain of Toronto etc.) would be good too.
Alternate lenses that show not just your cities but all cities within 6 and 9 tiles would be good.

Poorly defined. Within 6 (or 9) tiles of what?

lenses show a value of a tile (well at least some lenses do ... like appeal and settler and sort of tourism) .... in the case where a lens showed the number of cities within 6 tiles and one used a colour ramp from grey to bright green (like the appeal lens) then a tile with a low number of cities within 6 tiles would appear greyish while a tile with a high number of cities within 6 tiles would appear bright greenish .... a tourism type lens might actually be better with the actual count of cities within those distances being shown as a number. The whole point of this would be to make it easier to decide where to plop industrial and entertainment zones.
