Question about limits on displayed data in FortiOS

I have been working on a Fortigate that has over 7000 devices using it as a router and sometimes it goes over 7500 devices. I have noticed that some useful Dashboard widgets and FortiViews seem to reach a limit where they will no longer display more data. For instance the Device Inventory widget will only show up to 5000 devices and it seems if you filter the data it only applies to those 5000 devices. This causes an issue because there is a possibility if I am looking for a specific device it won't be in the 5000 devices that I can filter. I have noticed a similar effect with the DHCP widget but its limit seems to be 7500. Is there any way to increase these limits?
