Add Context to Embedded Task report

Hi All,

We're trying to embed an Appian Task Report in one of our Digital Portal. The task list (an Appian report) is supposed to show tasks for a particular Stakeholder for a particular Fund. Since we know the loggedInUser we can restrict the report to show tasks for a particular stakeholder group, however we want to pass an argument from our Portal to Appian when the user is on a particular fund to show tasks related to that fund. Is there a way we can achieve this by making an API call or by providing context to the report as an argument?

Thanks,

Arjun
