Is it possible to have a sys_sub_menu per page

Example: load one for all and a different one for only for when we are viewing a group page:

Example: http://demo.boonex.com/m/groups/view/Lane-Cove-Sustainability-Action-Group

Reason is that I want to center the caption and reduce gap between caption and breadcrumb with

div.sys_bc {

margin-top: -32px;

}

div.sys_page_header {

  width: 250px;

  height: 50px;

  margin: 1px 0 0 479px;

}
