I am afraid, but I don't know any other way to change those animations, the simple way was editing in your Object Builder.
You can try adding your client version in versions.xml (Object Builder file), after: <version value="1031" string="10.31" dat="52AED581" spr="52AED5A7" otb="54"/>
Find your dat & spr client signatures and add in there.
