iControl REST: Working with Pool Members

Hi Jason, While i have been able to use REST API Calls to get, modify, delete the Pool Members and create new ones in a Virtual Server. However, i have not been able to find out how to add one member to an existing pool which already has, say, 2 members. I have gone through the documentation and it mentions that POST has to be used, but it gives me error. PATCH and PUT overwrite the existing Pool members. Ex. - curl -k -u user:pass -H "Content-Type: application/json" -X POST -d '{"name":"myPoolName","members":[{"name":"MEMBERIP:PORT","description":"Server3"}]}' https://MANAGEMENTIP/mgmt/tm/ltm/pool/myPoolName gives an error - {"code":400,"message":"Found unexpected json pair at configuration item /ltm/pool/myPoolName. The json pair is \"myPoolName\":null.","errorStack":[]} While the following with PUT works fine but overwrites - curl -k -u user:pass -H "Content-Type: application/json" -X PUT -d '{"name":"myPoolName","members":[{"name":"MEMBERIP:PORT","description":"Server3"}]}' https://MANAGEMENTIP/mgmt/tm/ltm/pool/myPoolName Appreciate some guidance here. Thanks.
