It would be useful if a field template could inherit fields from another template by marking it as parent. That would allow creating a single base template with fields common to all products and new templates would just need to define its unique fields.
If possible a template should be able to inherit a template that is already inherited - giving it all fields from all parent templates.
Example: If a solution has 50 templates and a new field is needed or should be removed from all templates it would be a simple task if that field was defined in a general parent template.
We where missing this feature as well. But have solve it for now by handling it when templates are created in the code, where it all templates now inherits from a base template
