Wiki plugin required default post type is "Anyone"

Hi,

I am publishing all my wiki posts through wp ultimate csv importer plugin.

I bought wiki only for the reason of giving option of edit anyone. But i didn't see that option as default, i want it as default.

I want in default for every wiki publish post, with an option of edit anyone.
I don't want to open each and every post and choose wiki privileges to edit anyone. I want it to be default.

Please give me that option.

Thanks.
