In our ArcGIS Online organization most people need to work collaboratively with others in the system, hence, we need all of our users to be able to create Shared Update groups from the start. Please make it possible to assign the privilege of "Create with update capabilities" to a custom role, so that we can grant it to our users through New member defaults.
Currently, if that privilege is assigned to a custom role, then you are unable to select that role for use with New member defaults.
Manually re-assigning users to a custom role with that privilege, after their account is created, is not a scalable task for our administrators. (There are scripting workarounds, however, that is not a feasible solution for all organizations.)
[This Idea originates from comments on Make ‘create group with update capabilities’ a non-admin privilege, and I am posting it as its own Idea for increased, clearer awareness @JeffShaw @AmyWork3 @ReinaCMurray @PatIampietro @ColeWhite]
