Make all files-folders available for edit to team members

Is there a way to upload files and folders to Adobe Cloud that are immediately available to team members to edit without having to stop work to share a file to a team member where the file appears to only have 'read only' option. Sharing a file involves creating a link and emailing this to a team member which is tedious.

Have I got this wrong? Surely I, as admin can just upload files-folders to the cloud server and my team are able to access and edit without "being invited" or needing to receive a link?

Suggestions to make this sharing process far easier are welcome. Thanks.
