While monitoring AWS instances by using CA UIM aws probe the servers with robots were listed in the UMP with their OS host name but they are now displayed with their AWS virtual guest name.

Is there a way to always display with there host name where they have a robot installed?
UIM 8.51
discovery_server 8.51
AWS probe 5.34
