On WSA, is it possible to insert specific tenant ids on http header pointing on specific domains?
Can I do this via customheaders on advancedproxyconfig?
Yes it is possible and not that hard. Hardest part is dealing with all the issues with other 3rd party cloud apps that use Azure AD to login. If you figure that part out let me know :)

I cannot find a related topic on Cisco documentation. Could you please post a useful doc or link for me?
