Devices in submaps

Hi,

I have one main map (Global) with 2 levels of submaps (City, Building):
Global
–City
----Building

In the Building submap I have 2 devices.

When I look at the City submap it shows Building submap with 2 devices and their statuses, but when I look at Global map it shows City submap with 0 devices (so it does not show devices in nested submap Building). Is it possible to show these devices?

Thanks.

Petr
