Is there a recommended method for adding a one-time CAN poll to the queue with the response to be processed by IncomingPollReply?

For single-shot requests you can either use the synchronous `OvmsVehicle::PollSingleRequest()` method(s) or temporarily replace the PID list via `OvmsVehicle::PollSetPidList()`.

For the latter, you'd reinstall your standard PID list in the incoming handler once you've received the response.

What is the recommended method for adding or modifying obdii_polls after initialization?

In most situations you only need to switch polls partially or change the poll frequency. For this, use the up to four poll state timings per list entry, and call `OvmsVehicle::PollSetState()` to switch the current state.

If you need to fully replace a poll list:
  1. Lock the poller mutex
  2. Remove the current PID list
  3. Create / modify your PID list
  4. Install the new / modified PID list
  5. Unlock the poller mutex
For dynamically created PID lists and/or combining predefined with dynamic entries, use a C++ std::vector & std::initializer_list.

For a full example of this and also an example for how to do the PID list update, see the `vehicle_vweup` OBD module:
