On Skuid platform, please add the ability to add a reference field manually, including the Reference Key Field and the Referenced Object.
When you need to add a new reference field, the only way to do it is import. The import routine is fairly destructive to modifications you have made to the the Skuid Data Source. You have to document all your manual changes and re-do most of them if you import. By allowing the ability to add a reference field manually, you could add it manually and skip the import process.
On a side note, it would be great to review the import process and determine what really needs to be destructive, so we can avoid a lot of manual work.
