Combining get-adgroupmember with get-aduser

I just need a kick start here as I want to know if there is a better way to do this ...  B/c I'm running get-aduser 2x in select expression

 get-adgroupmember groupname | Select name,@{n='user';e={(get-aduser -identity $_.name -pr *).displayname}},@{n='mail';e={(get-aduser -identity $_.name -pr *).mail}}| ft -autosize

Thx
