You could either do it by making a union and then giving that an interior or
#declare an interior and use it in each object.  For example:

union {
sphere {<1, 0, 0>, 1 pigment {color rgbt <1, 1, 1, 1>}}
sphere {<-1, 0, 0>, 1 pigment {color rgbt <1, 0, 0, .9>}}
hollow
interior {
media {
ect.
}
}
}

Or,

#declare Media_example =
interior {
media {
absorption <1, 0, 0>
}
}

sphere {<1, 0, 0>, 1
pigment {color rgbt <1, 1, 1, 1>}
interior {Media_example}
hollow
}

sphere {<-1, 0, 0>, 1
pigment {color rgbt <0, 1, 1, .8>}
interior {Media_example}
hollow
}
