Exporting Multiple .dfs2 Variables to .asc

Hello,

I have a single .dfs2 output file containing water depth, x-flux, and y-flux.  I am familiar with the MIKE ZERO tool MIKE2GRID, which exports the water depth data to .asc, but how can I similarly export the other variables, x-flux and y-flux?  Using Release 2014, SP 1.

Thanks.
