Mount external storage in a specific subfolder


in the "External Storage" section one can choose the name of the folder where the external storage will be mounted (e.g. test).

Is it possible to mount it, not in a top folder (e.g. //owncloud/test), but in a sub-folder (e.g. //owncloud/my_external_mounts/test) ?

Thank you for any suggestion

No. But the user should be able to move it to whatever place he likes to have it. So you should be able to mount it and then move it afterwards to the folder in question. Can you try?
