'Add Activity' to Suggest Roles & Resonsibilities

It would be useful for a list of recently selected roles/responsibilities to be suggested when a new activity is added in the procedure editing tab. It's great to have the previous activity role/responsibility added to a new activity if the 'add activity' button is clicked while the cursor remains in the roles/responsibilities field, but I often find myself moving between similar roles/responsibilities for activities and needing to search each time becomes laborious when many roles (often similarly named) appear in the system.
