Turn Relational Link Into Inline Link
If you want to convert the inline links back to relational links, simply change property back to relation and connect the database. No links will break. As for more than one value inside the relation property, it will convert into multiple links, separated by a comma.
When To Use This Conversion
I would convert relations into inline links when a relational property is in-active. For instance, if a relational property doesn’t require any additional values from database it is connected to, minimize your relational use with this.
