Hide PCs belonging to a group

Hi to all...

is it possible to insert some PCs with the Teamviewer into a group of "controlled" PCs so that an administrator (outside this group) can access them directly but that the PCs in this group do not see the other PCs belonging to the same group?

For example:

PC1 and PC2 -> Administrator Group

PC3, PC4 and PC5 -> Controlled Group

From PC1 and PC2 I can access to all PC in the Crontrolled Group but from PC3, PC4 and PC5 I can't see the other PC in the group and I don't see the message to "the PC4 is connetted"...

Thanks...
