We use our own self-certification forms hosted on O365. We require staff and visitors to self-certify prior to coming into the office by completing our form. It would be great if the welcome message on the today page would accept HTML (like the e-mail templates) so we can link to our form from there. Same for the self-certify popup on the mobile app. Would be great if people could click thru from the popup to our own form.

Would also be nice to use some own corporate branding like a logo on the Welcome / today page.
