You can setup multiple OneDrive or OneDrive for Business accounts, as well as other cloud storages.
To setup multiple accounts, create a site profile for the first account as normal.
Next, go to Internet Explorer/Edge and log into the same account and then log out.
Then, create the second account site profile in WebDrive.
Now, you can connect both.
You can continue this for any additional site profiles to be created, just ensuring to log in through Internet Explorer and then logging out for each one.
