It would be very useful if the Boolean field would automatically activate only when a series of fields are complete with data

Practically:
I have a library with various fields where I have to enter data, these fields are not all completed at the same time but on different dates. So by inserting a Boolean field (yes/no) with an example title, "completed data", I would like this Boolean field to be activated automatically when all the fields are complete with their respective data. This allows me to split the library data into completed and uncompleted.
Confident for a positive response, thank you for your attention.
