Lazy-All and Export

When exporting from advanced search>filter with a list of tiddlers it will only export the _is_skinny version of the tiddler when start up is configured as root-tiddler=$:/core/save/lazy-all. Assuming the tiddler hasn’t been opened.

Is there a method to trigger the lazy loading for exporting a set of tiddlers as json? I’d rather not open 78 tiddlers per date that I want to export.
