How to tell continuum to force checkout

[Mordo, Aviran (EXP N-NANNATEK)]

 

I'm running a continuum on a build server, but I'm getting a message
that the build fail since it could not checkout (Got some conflicts)
from starteam and I need to use force checkout.

Is there a way I can add parameters to the scm element. I want to be
able to tell Starteam to use -o option to force checkout. 
How can I do that ?

Thanks,
Aviran
