Creating calendar all members can edit

We are creating a calendar for the 3 full time missionary companionship's dinner schedule and we would like each ward member to be able to create an event. Can we allow all members of the ward to edit a calendar without inviting each of them to the calendar?

The LDS.org Calendar is not set up for this particular scenario. Only members added as editors either by name or by calling can edit a unit calendar. You made need to find another resource to accomplish this task. Based on other threads addressing this same scenario have indicated the solutions offered were quite labor intensive.

A couple of options are discussed in this thread. We have not used the Missionary Dinner Calendar site in our ward, but it looks pretty easy to set up and manage.
