Is it possible to disable Chat Waiting Time, or to make it indefinite?

We have used many online chat services over the years. However, Zoho's SalesIQ appears to be the only one we've tried that has a mandatory time limit where we must respond to new customer queries. We are a small business so we have no dedicated staff to monitor incoming chats, which makes this requirement very undesirable. (There have been no complaints from our clients when we're slower to follow up.)

Is there an option I'm missing to turn Chat Waiting Time off, or to allow an infinite wait time? I haven't been able to find one so far in the app's user interface or accompanying documentation. If such a feature is unavailable, may I request it be added?
