Configure 10/100/1000 port to autonegotiate to only 10 or 100?

Scenario 1

2960-X-switch ----> (patching) ----> Paying client 

Scenario 2

2960-X switch ----> (100Mb switch) ----> (patching) ----> Paying client 

Is there any way to configure a 10/100/1000BaseTX port on a Cisco 2960-X switch to negotiate only at 10Mb or 100Mb? I'd like to provide a 100Mb connection to a paying client (who has paid only for 100Mb) via Scenario 1. I'm aware I could use

speed 100 duplex full 

but that would disable auto-negotiation and I'd prefer not to have to impose configuration requirements on the client equipment. The only solution I've found is to use Scenario 2, which introduces another point of failure, but will indeed work.

Is there any way I can get Scenario 1 to work? To configure a single port on 2960-X to autonegotiate, but prevent it negotiating at 1Gb speed?
