Yes, but...

1) You have to assign it the ring tag.
2) You cannot assign two different tags to the same structure. So either 
you have to make this a std::deque or so, or (probably more convenient) 
derive two different structs from your std::vector<my_custom_point> and 
register them separately. The derived structs do not have to add 
anything. Just deriving and registering must be enough.
