default Fall-Through = Yes for groups

Guys, Is there an option to set Fall-Through = Yes for groups as default, just wanted to avoid having Fall-Through = Yes in every group I have in radgroupreply. So if a user is a member of three groups I didn't want to have to put the Fall-Through attib in at least the first two groups, so he inherits the attibs from all three groups, thought there might be a setting in a config file for Fall-Through defaulting to Yes for groups, but couldn't see one.
