Choosing a different library from SharePoint Online to link as a repository

Has anyone using the SharePoint Online connector been able to select a different folder to the default 'documents' folder in their SharePoint site to be used as the respository? I have tried multiple combinations between the server address and the repository name to try and get the connection manager to connect to a different library within our SharePoint site but always get the 'FrameMaker could not connect to the repository' error.  Using FM22 v17.0.4.
