Enhance the Ref Dialog 'File Name' input box to handle folers. It would be great to have the option to convert the Folders into internal 'container' models in the active dgn, and nest their files as attachments (or Cells?) there. Please also provide associated keyins.

Ref attaching a folder this way will help manage federated models that are common on Mstn projects. Nesting, grouping is currently done by loading and editing the Ref attachments in each dgn. Any changes in Ref composition will entail loading and editing multiple files. Much more effective to just add, omit the files in the folder, which would then be attached as required.

See previous discussion.
