Two fields instead of single NullTime for _at colmns

[Luit]

I was wondering if it would be possible to have optional datetime/timestamp colmns work as two separate fields; a boolean field and the timestamp itself.

For example, when using a soft-delete and registering that in a nullable timestamp column called deleted_at, fields Deleted bool and DeletedAt time.Time instead of a single DeletedAt sql.NullTime.

Would that be possible to have sqlc do?
