Entity naming conventions changed in recent updates?

Hello,

Recently I tried to add a new device to my network and I noticed that the associated entity names were named differently than I had expected.

When I set the network up about 2 years ago, the naming convention was:
entity_name_XXXXXXXX where XXXXXXXX is the hex hardware address.

Now, when I add a new device, the naming convention is: entity_name_1. A similar device after that would be: entity_name_2.

Is there a way to go back to the old way?

Thank you.
