If you layer is themed like this

 Property = 'A' - Style for this rule
 Property = 'B' - Style for this rule
 Property = 'C' - Style for this rule
 Property = 'D' - Style for this rule

You "explode" it so that you have 4 layers like so

Property_A
 - Filter: Property = 'A'
 - Default style: Style for this rule

Property_B
 - Filter: Property = 'B'
 - Default style: Style for this rule

Property_C
 - Filter: Property = 'C'
 - Default style: Style for this rule

Property_D
 - Filter: Property = 'D'
 - Default style: Style for this rule

This way, your 4 layers combined will still look like the original themed
layer, but with each "style" individually toggle-able.

MapGuide Maestro just so happens to support this exact scenario for
exploding themed layers.
