Archive chatbots and not count toward plan

We use chatbots for our various trade shows, it would be nice to mark the chatbot inactive or archived and be able to keep them for a period of time, but not count toward our plan limit so that we can still access the data. These chatbots are only used for a period of time and we have various shows, so I have to delete the past show chatbots in order to create the future show chatbots. If I wanted to look at historical analytics, I wouldn’t be able to because the chatbots have been deleted. So it would be nice to not have “Inactive” or “Archived” chatbots count toward the plan.
