@Anthony that option does exists (to force renew all) but that’s not the best approach (it’s perhaps ok if you just have a couple of certificates). If you wanted to basically control renewal manually you can uncheck Certificate > Advanced > General Options > Enable Auto Renewal.
The better approach is to let the certificate auto renew (a new cert if requested and stored) but set the deployment task (in v5 or higher) Trigger to Manual. You can then either run the deployment of the latest certificate on demand via the UI or scripted as a scheduled task that you create and manage yourself.
