The way my site works is based on member level. At each

The way my site works is based on member level. At each level they can do different things or more of the same. For example, I want to have users and 1st level be able to post/edit 1 ad for as long as there membership is active. Members at 2nd level can post/edit and maintain 10 ads for as long as there membership is active and so on...can I do that with this?
