GDML shape names

Hello ROOTers,

When I import a ROOT geometry to a GDML file, integer suffixes are automatically added to shape names. For example,

       <xtru lunit="cm" name="BGO_Wide_99625968">

<twoDimVertex y="0.6" x="-3.6"/>
<twoDimVertex y="1.0" x="-3.2"/>
<twoDimVertex y="1.0" x="3.2"/>
<twoDimVertex y="0.6" x="3.6"/>
<twoDimVertex y="-0.6" x="3.6"/>
<twoDimVertex y="-1.0" x="3.2"/>
<twoDimVertex y="-1.0" x="-3.2"/>
<twoDimVertex y="-0.6" x="-3.6"/>
<section zPosition="-9.0" scalingFactor="1.0" zOrder="0"
xOffset="0.0" yOffset="0.0"/>
<section zPosition="9.0" scalingFactor="1.0" zOrder="1"
xOffset="0.0" yOffset="0.0"/> </xtru>

99625968 is attached to "BGO_Wide", even though I named the shape as just "BGO_Wide". Is there any way to prohibit the exporter from attaching prefixes? When I run Geant4 with different GDML files in order to optimize my geometry, I always have to remove the prefixes in my analysis.

Thank you in advance.
