Dynamics SharePoint OOTB - Specif folder

Hello, 

Using the OOTB CRM online - Sharepoint online interface, is it possible to store CRM document under a specific folder of the Sharepoint site?

The site address is mycustomer.sharepoint.com/.../SITEA

and I would like to store CRM under the SITEA/folderA/FolderCRM

Then CRM would create folders as needed.

When I try and put the url to the Site and subfolders instance this doesnt work, only sites are accepted.

Any idea how to achieve this?

thank you
