Force usage of two resources for a task

Hello,
I am evaluation Projeqtor for my company and it is really a fantastic tool!!
So far, I have been able to do almost exactly what I wanted.
I have a question though.
I would like to know if it is possible and how to create task that needs eg a Machine (physical resource) and a human to complete.
I have created a tool (say hammer) and a person say Joe. In order to complete a task "putting nails" I need both the hammer and Joe.
If Joe is unavailable on Friday, I can't use the hammer to work on the task that day.

Or if the hammer is used on another task by jane, Joe can't work...

Is there a way to do that?
Thanks,

RG
