Thanks Lewis, you’re absolutely right.
The good news is that a major project to handle multi-turn batches is already in progress 
It’s been asked for many times in the past, but strangely has never been asked for here on the community (which is the best place for requests like this), so thank you for opening this thread.
I can’t guarantee it as we’re still in the early stages and there are a number of unknowns still, but we’re expecting this to be ready in the next 4-6 weeks. Update: This is taking longer than expected, but don’t worry, it’s progressing well and we’re working hard to have it completed as soon as we can.
If anyone else would like to see this, please vote above and add any extra comments or related suggestions and we’ll do our best to incorporate the suggestions.
