Refreshing available commands for existing devices

[teewee3]

Hi,

I have a Denon AVR with two zones. In harmony the zone 2 is added as a separate device, but for some reason with a lot less pre-configured available commands than for the main zone even though the same remote is used for both.

When teaching the missing commands to the harmony hub from the original remote via IR they are appearing and working fine in the harmony app but are missing in homey.
I tested adding a new device via the harmony hub app in homey and the recently added commands will then become available. However, the device will appear as a duplicate - once with only the old commands and related existing activities and once as a new and separate device without any activities.

So here comes the question: is there any way to refresh the list of available "send command" commands in homey without having to re-add an already existing device?

Re-adding every time new commands are taught will potentially lead to a lot of duplicates and confusion, and alternatively when deleting the existing device and then adding it back all acitivites will have to be updated with the new device. I already tried this once and the acitivites/flow cards for this device all show "missing" even though it is the same decive (but apparently with a new identification code?)...
I also tried restarting both the harmony hub and homey without luck.

Thanks in advance for getting back to me and for a great and very useful app!
