Workspace cleanup too many objects

Is there a work-around here for this situation?

Customer has a single workspace of more than 100 objects.

MUCH more.

At the root level they have a half-dozen or so folders and about 20 Sheets/Reports/Templates.

Under each folder, there are one or more folders and one or more objects.

The limit on Save as New of the Workspace is 100 objects.

We can Save as New on Folders, but those are done individually, and also subject to the 100 object limit.

Individual objects can not be combined into a batch Save as New. Work-around is to move them into a temporary folder and Save as New on that, and then move them back out.

I'm looking at dozens of Save as New operations.

Is there a better way?

...

Here's what I am trying to accomplish -- cleanup this garbage.

Here's my proposed plan of attack.

1. Save as New on the Workspace. Twice. 

2. In Workspace #1 - delete objects that match a certain criteria.

3. In Workspace #2 - delete objects that do not match that criteria.

(basically, splitting the system into two workspaces)

Repeat 1-3 until I have separated all objects in original Workspace into many individual Workspaces, all while keeping the original Workspace intact.

I want to do this with as little "thought" as possible but more importantly, this seems quicker than performing the Save As New on each piece now. But it looks like I will have to do that anyway because of the 100 object limit.

Also: There's also an "unexpected error" on one of the Folder Save as New operation. (I'll contact support on that one). It isn't limited to Dashboards (I'm testing the concept in a Team account).

I've also have an error when trying to do this with the API. I'll add that to StackOverflow too.
