make BGPSession "name" an optional field

Is your feature request related to a problem? Please describe.
Hi, since the "name" does not have to be unique and the BGP Session is already unique by specifying the below:
device, local_as, remote_as, local_address, remote_address

would you consider changing the "name" to an optional field?

Change the BGP Session "name@ to an optional field.

Hi,
fully agree with @mkurjanski to make session "name" as an optional field.

Is there a field to add the local and remote devices?
