[Koha] 3.16 for a consortium set up

[GCL NGLG]

Dear All,

We are currently testing Koha 3.16 as part of a 3 College consortium.

Is it possible to hide search returns at item level when searching across a
Group of Libraries?

Group A - 2 Libraries
Group B - 3 Libraries
Group C -  1 Library

That is, when using the pull down menu in the opac, setting it to Group B
it will only return titles and items for those 3 Libraries?

Many thanks.
