How to add a second OneDrive?

Hi, I’m using the android app and I was wondering if it is possible to add a second OneDrive and use them both at the same time without logging off and back on. Tried to set up a second one using WebDav but didn’t succeed.

Same question here.
Specifically: have OneDrive and OneDrive for Business with both using the same log-in name but different password. When logged in at OneDrive and then trying to set up the next vault in OneDrive for Business I don’t receive a log-in page anymore and am immediately connected to the OneDrive.
I can of course log out and in again with the OneDrive for Business account, but then the first one is locked, of course.
Besides: OneDrive for Business does not connect at all, but that is a separate issue.
