no parameter for auth token

[JuneChoo]

Hi,
Thanks for reading this issue.
I'm using my Developer account (developer access key and secrete key) to request data from my Seller account on MWS. According to the terms, I should use auth token from seller account to access, but it appears that boto doesn't have a parameter for entering auth token.
Some one addressed this issue before, but still unsolved.

Useful to me as well, saved debug.
Is there a way to pass MWS Auth token as well ?
Thanks for reading this issue
