Automation to take action when all columns in a board are not blank

The use case here is: Board admin/user creates new item in an existing board having multiple columns (of different types like text, date, person, choice etc’…) that needs to be populated. Only after all columns are updated the status in this board should change and trigger action of other different users in other boards.
So requested logic would be:
If all columns are not blank then change status and create item in a board and connect boards.

Thank you!
