LocalLB.NodeAddressV2.set_description() transaction support?

For example:

f5_start_transaction(b)

f5_set_active_folder(b, folder)

f5_add_pool_member(b, poolname, ipportseq)

f5_set_node_description(b, address, description)

f5_submit_transaction(b)

Doesn't work...

=== Exception Details ===

Server raised fault: 'Exception caught in System::urn:iControl:System/Session::submit_transaction()

Exception: Common::OperationFailed

primary_error_code : 16908342 (0x01020036)

secondary_error_code : 0

error_string : 01020036:3: The requested node address (/test/1.1.1.6) was not found.'

but this does:

f5_start_transaction(b)

f5_set_active_folder(b, folder)

f5_add_pool_member(b, poolname, ipportseq)

f5_submit_transaction(b)

f5_set_node_description(b, address, description)

The operative difference being that the node address we are trying to set the description on is created and submitted as a transaction before the node description is set.

My understanding is that I should be able to bundle all these set type actions into one transaction...
