Is there any morphia query to achieve $geoWithin and $centerSphere mongo Operations?

Question

The existing Morphia Query:

q.field("somefield").within(addressLatLng.getLat(), addressLatLng.getLng(), degrees);  

which gives a Mongo query like

{ "geo" : 
 { "$within" : 
  { "$center" :
    [ [ 38.8987037 , -81.52672820000001] , 4.341534008683068E7]
}}}

But this makes our application slow on loadtest, it takes around 400ms to execute, whereas the Query with mongo operations $geoWithin and $centerSphere query execute much faster about 9ms.

This the Mongo Query:

{ geo: 
 {$geoWithin: 
  { $centerSphere: [ [ 42.0494171, -80.0423151 ], 0.00758341759353 ]
}} } --- 

I need a morphia query for the above stated Mongo Query, I have searched in morphia's documentation but there is no such API for $geoWithin and $center.
