Can subitems for zombie loadouts have probability?

[local306]

Is it possible to use the XML markup for probability inside of a subitem branch?

 

<m_items>
  <itemGUID>cbe793fe-97d9-4585-88e0-bc18be39d714</itemGUID>
    <subItems>
      <probability>0.25</probability>
      <itemGUID>48efaf62-6a65-474a-8773-886e05ea7632</itemGUID>
    </subItems>
</m_items>

 

In the example above, would this work such that one of these items would guarantee to be on the zombie, but Item A (main item GUID) would appear 75% of the time versus Item B (subitem GUID) spawning 25% of the time?
