Multi Entity - shared Custom Fields - entity wise default and picklist values

[sHruschka]

For multi entity environment it should be possible to define global shared custom fields but with entity wise default values and in case of picklist values entity wise picklist values.

For example, we have fields which are used in every entity, but have different default values per entity, currently we cannot configure this in Zuora.

Same for the picklist values, it should be possible to define a set of picklist values per entity without losing the comfort to have a shared custom field.
