Different levels of read / write licenses

Wish that as the main administrator I could control more specifically what read / write users should be able to do. Want a group to be able to edit amount and risk assessment but I don't want them to be able to add and remove safety data sheets from lists or add and remove sites. However, it is good if they can edit information for the site for which they are authorized. There should also be a group that can only edit amount but cannot perform risk assessments, edit location and so on.
