Much like we have a "Contact Ownership" option when importing a CSV Mailing List, customers are requesting a "List Ownership" drop-down option so they do not need to manually change it after importing their list.
It will save time for users to be able to set both the list and contact ownership at the same time when importing their list in the UI rather than importing, confirming, searching for, and updating the List Ownership.
