how to change or delete sub-element using SDM Rest API

Hi All,

I can use the SDM Rest API (NNC82) to add one session agent group.  However, I am unable to find a way to modify the sub element (sipDest) on it.  Can anyone please help?  It will be much appreciated if you can advise the JSON format of the request body?

for example, I can create following session agent group.  When I want to remove 7.7.7.7 from dest, or want to change the order of 7.7.7.7 and 8.8.8.8,  I am unable to achieve it.

session-group

group-name sagtestgroup

description test sag

state enabled

app-protocol SIP

strategy Hunt

dest 7.7.7.7 8.8.8.8

trunk-group

sag-recursion disabled
