There is no per page option for upload locations. Users with general upload and browse permissions (as defined in Site Settings > Security > Permissions) can upload and browse starting at /Data/Sites/[SiteID]/media.
Users who only have permission to upload to a user specific location can browse and upload beginning at /Data/Sites/[SiteID]/userfiles/[userid]
Admins by default can upload beginning at /Data/Sites/[SiteID]/
However you can force admins to start at the media folder by adding this to user.config
<add key="ForceAdminsToUseMediaFolder" value="true" />
These settings are not specific to any editor, they apply to all editors.
Hope it helps,
