Calendar resources - Add group of resources

[NickArbo]

Hi,

we are adding audiovisual resources in our calendar. We add them individually but is it possible to add them as a group as well?

For example, we add resources : A,B,C,D,E

But I would like to add also

resource #1 that contains resources A,B,C

and add resource #2 that contains resources B,D,E

etc

Am I clear? How can we do this? Thanks
