If you have a completed WISP and you want to change the officer signatories, you will need to create a new WISP. To create a new WISP from a current Active WISP, click on the "Build my WISP" button in the upper-right corner. This will provide you an option to select your starting template.
Choose "Use my active WISP as a template." This will allow you to utilize the draft of your current document, and update any roles you would like. After you have made your changes, you will need to go through the process for electronic signatures to finalize and activate your new WISP.
