Pass attributes to report generator

[vijay]

I have

taskreport milestones "" { 

.....

 scenarios ...   
taskroot project.milestones

}

followed by
taskreport overview "" {
...
<[report id="milestones"]>
....
}
Can I pass the scenario names to the report generator? Whats the syntax? e.g. I want to do something like

taskreport overview "" {
...
Our current plan is...
<[report id="milestones" scenario="plan"]>

If we hire a team in Bangalore then the plan would be
<[report id="milestones" scenario="offshore"]>

....
}
