Editing a script task using built in designer

[maudrid]

I'm not sure if this is a silly question, but using the activity modeling/designer tool as part of activiti explorer in v5 or the new activiti app in v6 beta, I'm not able to find a way to set these properties of the script task:

activiti:resultVariable=
activiti:autoStoreVariables="false"

Without exporting the bpmn20.xml, adding it in and then importing is again, is there a way I can change the value of these using the provided tools?

They seem indeed to be missing.
However, you don't strictly need them. You can set the resultVariable yourself in the script using execution.setVariable('myVariable', value);
