Help with showing different LiDAR returns in mosaic dataset?

I would like to use a mosaic dataset that contains LiDAR data to show both a first return and bare earth surface.  The "LAS Dataset to Raster Function" help file contains the language posted below.  I've successfully created a first return surface with a 3-meter cell size using the Raster Type Properties dialog box (attached), but I don't see how I can use caching to show a different return or the ground class only.  In other words, how do I get access to the return types and class types to choose what surface I want to show since I've already selected "Any" for both types.  I am using the Triangulation radio button to take advantage of the constraints in my .lasd file.  Is the parenthetical that says ''no caching" throwing me off?  Any help in the process is appreciated as this will eventually be published as a service in ImageServer. 

Number of cached surfaces�??The maximum number of caches that can be created using different properties (in this dialog box) for this surface. For example, you might add the LAS dataset to create a surface displaying all the points but you also want to visualize only the points that are classified as ground from the same dataset; therefore, you can create two caches to visualize this data in two ways. Entering a value of 0 will disable caching or clear an existing cache.

............................
The cache will be updated in the following scenarios:

The input has been updated.
The cache has been deleted or is missing.
The function parameters are set to define a different surface than the one that matches the cache (for example, use a different Return type).
