Cant seem to automatically post multiple stacks at once, can only do single stacks 1 by 1

I thought this was on purpose because of the hardware event requirement for each posting, right?

Yes. It is possible to post multiple stacks automatically using the api only when they don't make more than one full stack when combined, but in other cases aux would have to prompt you for a hardware event each time before it posts a stack. For now this is my preferred solution as it's more consistent.
