Can LDS Tools do this?

[RayMcAllister]

Two pairs of full-time missionaries serve in our Maryland ward. For evening dinner appointments with members, they cannot leave their respective assigned proselyting areas. Can LDS Tools keep track of that boundary, which zigzags across the ward, so that members can tell at a glance who lives in which area, when they sign up to feed the missionaries? How have other wards solved this problem?

Can LDS Tools keep track of that boundary,

I do not believe so. You might keep a small map with the meal signup sheet. Or post the boundaries on the bulletin board.
