Health Check Internval reduction

One of our customers is asking for a large decrease in the re connection time in a SF tunnel when a WAN link has dropped.
Now it takes around 10 to 15 seconds for the dropped WAN link to become part of the SF tunnel again.

We would like the ability to decrease the Health Check Interval to a lower value than the now lowest one of 5 seconds for the re connection time to be reduced.

Thank you!
