Feature Flag target discovery

I have a very short running process that I’m using feature flags in. This is is node.js. I create a client. It appears that whether I assume streaming or polling that it’s polling. But when I select polling it appears to at least do the first poll right away, whereas the streaming interface polls after the polling interval. My issue is with target registration. When I request a flag the target is only registered on the next poll. Meaning that unless I wait for another poll iteration the target never gets registered.

What is the way around this other than to set a very short poll interval? Is there a way to force a check?
