Allow override Display Name?

[mlasevich]

When using with Keys, the DisplayName is semi-ugly, but bearable... but when using with Role ARN - the display name gets to be insanely long. Can something be offered as an alternative? Either shorten the ARN or offer to display alternative string (like ID?)

For example, instead of current:

AKIAXXXXXXXXXXXXXXXX:arn:aws:iam::999999999999:role/MY/VERY/LONG/PATH/My-Long-Role-Name

something like one of:

• My-Long-Role-Name
• My-Long-Role-Name@999999999999
• (or, like i said, just offer a custom field?)
