Documents in Rooms read only

Hi,

We have created a room using SAP Standard Template. This room has a documents folder which is accessible by all room members i.e. all the room members have the permission to create, modify and delete folders/files in this folder. Our requirement is to restrict this access. We would like to give full permission (Create, modify and delete) to the administrators(room owners/creators) and give read permission to the rest.

Is this possible?

any kind of help/suggesion is appriciated.

Thanks

Smitha
