How to take screenshots from only one monitor in Elance Tracker?

Question

Freelance

Good evening!
There is such a thing on Elance (and not only there) - Tracker. She counts the time spent on work, periodically takes screenshots and publishes them in the project.
My desktop is extended to two monitors.
I would like to know if it is possible to force her to take screenshots of not the entire desktop, but only one monitor?
Thank you for your attention.

Do not want to take screenshots - work through a fixed price. How can you trust an employee if he is not ready to show what he is doing during work, but asks for money?
Fortunately, there is no such thing in Elance. The Odessa client has such functionality, its meaning is not clear.
