Relation between module records depending on module ids.
It is very important you add this feature. It will be better that it will be possible to make relations with parent modules via passing parent module ID in a lookup field when inserting or updating some record via API. For example if I create my custom module and i want to add a record into it via API it is impossible to make relation between this record and lead bi lead_Id. For now only by lead name. This is unusefull because lead name can be repeated in other leads.
