Yes, you should be able to create a counter which publishes its initial value of zero. I'm fairly sure I've done this with the Golang client some time in the past. What language and client library are you using?
You'll have to initialise the counters explicitly. If the first time the client library knows about the counter is when you increment it, then clearly it won't be able to export it until then.
