Option to Disable Bandwidth Allocation in DumaOS

I personally live in an environment which has a constant flow of devices and recently got an XR500, I noticed that this router was performing  well for the first few days but then began seeing a number of issues involving extremely slow connection speeds. I found that this was caused by the mandatory bandwidth allocation requiring the division of signals by percentage. In a household with 5 devices I would not see this as an issue but when bandwidth is split across 10-20 devices at all times this is a major issue, because of the way DumaOS behaves, it constant attaches new devices to the division and does not remove them when they go offline resulting in an excesivelly minimized connection. This connection which could start at say 100mbps is already at 10mbps once 10 devices have ever connected. At 20 it is only 5mbps, and so on.
