There will be some new apps and features added in 2018 and beyond. I cannot say for certain if support of SSO will be included. I do know that this is a feature that has been discussed and is being considered.
We do support Scan to OneDrive for Business. When using the App Studio apps, users should be asked when launching the app at the device if they are using a Personal or Business account. Also, the Scan to Office 365 app supports connection to OneDrive for Business.
We appreciate the feedback. Please keep it coming our way.
