vrrp faster backup

Dear All

I'm a new comer in IETF.

VRRP [RFC 3768] specifies an election protocol that dynamically assigns 
responsibility for a virtual router to one of the VRRP routers on a LAN. 
This election process provides dynamic fail  over in the forwarding 
responsibility should the Master become unavailable. 
 
The router survivability capability provided by the Virtual Router 
Redundancy Protocol requirement: (3 * Master_Adver_Interval) + Skew_timer 
for  Backup Router to declare Masterdown in the VRRP [RFC 3768].
It will be more than 3 second when the Master_Adver_Interval was 1 second. 

In some LAN environments, the Backup Router needs faster method to declare 
the Master Router is fail.
As if (2 * Master_Adver_Interval) + Skew_timer or (1 * 
Master_Adver_Interval) + Skew_timer. 
Are there a message type which permits the Backup Router could backup 
faster?
 
Best Regards
