Virtual-Template for l2tp subscribers


There is Virtual-Template interface for l2tp-sessions exists, on Cisco routers for example.
It is very usefull for LNS with several thousands l2tp-sessions. So parameters from Virtual-Template are inherited to Virtual-access interfaces.
For example, tcp adjust-mss for l2tp-subscribers.

But I haven`t found such option in VyOS. I mean something like Virtual-Template approach. Is it possible to create feature request for it ?
