Can I create a 10.1 Mosaic Dataset that references Workstation Grids?

[MarkZweifler]

When I use the 'Add Rasters to Mosaic Dataset' tool pointing to a workstation grid workspace I am getting the following error message;

[INDENT]"Error: 8004205f: No new mosaic dataset item was added".[/INDENT]

I have been unable to obtain any information about the Error ID. 

Does the Mosaic dataset supports GRIDs at 10.1? if so, any ideas what Erorr ID # 8004205f refers to?

thanks

In playing around to try to create this mosaic dataset it seems that  the problem is related to the "Advanced Options" > 'File Filter' option.

When i attempted again after removing unwanted grids from the workspace and then using the Add raster to Mosaic' without using a filter, the tool successfully added the thematic, single-band ESRI grids to the Mosaic
