Yes. The content included/shown on the Medusa page is the same in the updated UAccess Research System. It just has a different look and feel.
You will still have the options of displaying Proposal > Award where the Proposal is the top item and all awards, negotiations, and subawards associated with the proposal fall under it, or Award > Proposal where the Award is the top and all proposals, negotiations, and subawards associated with the award fall under it. You can expand each item by clicking on it, and have the option to open each item directly from the Medusa page (as long as you are provisioned to view that item).
