Concatenating enumerated types in coverpoint

Hi,

I will explain my query with an example. 

AddrHigh is a 16-bit address which is enumerated as NORMAL, DEVICE etc.. AddrLow is also a 16-bit address which is enumerated as TIMER, UART etc..

 I want to concatenate AddrLow and AddrHigh, and declare bins like below. I don't want to specify binary values instead I want specify bins using enumerated names. Is it possible? If yes, what is the syntax?

 a: coverpoint {AddHigh, AddrLow} {

       //bins

   }
