Can't add or change record summary using form definition?

Can't add or change record summary using form definition?

Hello,

I am trying to copy all changes from one app to to another (the first app is used for testing new features, and the second app is actually used by the users).

I have some record summaries that I want to copy to the second app, but when I enter one into the Form Definition script and save, the changes are not saved.

I would very much like to avoid remaking these in the editor because they aren't small (and I hate using drag-and-drop editors).
Is there any way to copy or modify the record summaries in the form definition, or some other way to just paste the contents?

Thanks
