Insight: Data of old interfaces

[Mr.Goodcat]

Hi!

Recently I removed a NIC from my OPNSense Box, resulting in new interface names for the WAN/LAN ports. This causes the traffic data gathered under "Insight" in the "Reporting" category, to be inaccessible. While the data is still being shown in the plot (like in [1] - in my case as "15" and "igb5"), the old interfaces can't be selected as the "top usage ports" and also can't be exported. Would it possible to update OPNSense to enable the selection/export of old, currently non-existant interfaces which are still contained in the database? Joing the data with new interfaces would be even better.

Thank you and have a great new year's eve!
