Modifying subtask columns showing in parent issue view

We would like the ability to modify the columns that display for subtasks within the parent issue view. This is possible with standalone JIRA, but does not seem to be possible with OnDemand. We would like to be able to select from both standard fields and custom fields. We would like to be able to also control the position of each column in the subtask view. Finally, if more columns are chosen than will fit, we would like a horizontal scroll bar to automatically appear, so that we can quickly scroll to the right-most columns.
