Ability to choose if a field is bi-directional for Entity and Multi-Entity types

Hi,

We often realize some time after having created an Entity link between 2 entities that it is uni-directional and that we want to replace it with a bi-directional link.

We also once created a Mutli-Entity field just to have the bi-direction to realize later that someone has put several entities in the field when we wanted only one to be linked.

So I think it would be really great if the notion of uni/bi-direction and the notion of uni/multi-entity were separated in Shotgun.
