yes, it is.
it's a SMOP:
a) update the polling method on the nodes
b) add and remove the required pollers to the nodes
You'll have to ask something more specific after you've written some code to try this -- computers allow you to make bigger mistakes faster, and the SDK can allow you make some very big mistakes.
Can I ask what an SMOP is? I think you are saying that I cannot change directly but have to almost re-add?
