BI Aggregations using regular expressions

Hi, I am trying to develop some BI aggregations and am trying to use the $HOSTALIAS$ for creation of the nodes in the aggregation. I have not been successful in doing so with only $HOSTNAME$ being the only expression I am able to successfully use. My understanding is that the use of Alias was supported everywhere host name is. Am I doing something wrong or overlooking a config? I am relatively new to CMK, so any assistance/feedback would be greatly appreciated.

You can enable the in-place help by hitting the small book button on the upper right corner:
