Using a List View Button on Obj1, create new records in Obj2 (based on selected records in List View). Ideally this would create unique records by Account. For example, if 5 records were selected associated to 3 Accounts in total, only 3 records would be created in Obj2.
I have looked for posts on similar inquiries but haven't found anything matching this use case with a confirmed answer if it's even possible or not.
Any help/guidance/programming help is greatly appreciated.
