How can i reduce the Output of "Get-QADUser Username | Format-List LogonName, MemberOf" => MemberOf should be only the Name an not CN

Get-QADUser Username | Format-List LogonName, MemberOf gives me:

LogonName      : UserName
MemberOf       : {CN=G-Usr-XXX-XXXXX-XXXXXXXX-Write,OU=XXXXXX,OU=XXXXX,OU=XXX,DC=XXXXXX,DC=XX, .......  ...}

What i am looking for is:

LogonName      : UserName
MemberOf       : {G-Usr-XXX-XXXXX-XXXXXXXX-Write, Next Group Name  ...}

Another thing ist, that if there are many goups they are not listed all! just a ...} at the end. How can this be solved?
