Personalisation rules on site level

Dear,

We are struggeling with the personalisation in Episerver. In our setup we host multiple brands/sites under the same root folder.

At the moment personalization settings/target groups are defined at root level, meaning they apply to all. In our setup this doesn't work. Therefore we would like to ask to make it possible to define target groups & personalisation settings on a site level rather then on root level.

Best regards,

Arne
