Mass Maintain for Member Acess Profiles for BPC 7.5 NW

Dear Gurus,

We have almost more than one hundered member access profile in my project.

Version dimension are available on our input schedules.

Business requirement is that change to read right from write right for current version and all user. My question is that should i have to manually maintain for each member access profile or is there any way to do it automaticlly for all member access profile ?

Thanks and Regards,

Alper
