How do I create a choice field based on a table?

I have a shared list of choices between views/forms and I don't want to redefine them everywhere they are used. The UI appears to only support a static list entered at field creation or update later.

I want that choice list based on another table's content.

@Lee... Currently, that is not possible.   I believe there is an enhancement request to support it.   For now, you have to do that through a table relationship.
