Sending ROI

Hi

I sent my client the Release of information form in the initial intake paperwork- it was unclear to her that she needed to actually add names to the releases so she sent it back to me blank. How do I ask my client to fill out multiple ROI for her family and other treaters through the portal? is there a way to make this a part of my intake paperwork for more than just one person? I am totally lost- thank you in advance for any help -Sarah
