I've developed a number of apps for the iOS devices, and now I'm doing freelance work for other companies as well. We're at the point of getting all the certificates created, and I'm not clear on the right steps to take.

I've been invited -- and joined -- the client's Development Team in the iOS Provisioning Portal. There is no Development Certificate for me, however.

Do I need to go through the entire process again to get a new certificate issued, or is there a way to "reuse" the existing certificate I've already got.
