It would be great to have the option to select geometry within different proposals and have them echo (or mirror) sync to one another. To better explain, i am creating 6 proposals and a specific road on all of the proposals must be consistently the same. When I get to the 6th proposal I decide to change this specific road and alter the geometry. Now I must copy this road and paste it into the previous proposals for them to all match. If the road has a feature to sync to other proposals this would speed up the process of having consistent matching data across proposals as desired.
