Bgp advertise-peer-as prefix (mirroring by add community)

Feature requests

Hi.
I have studied the documentation and have not found a solution. is it possible?
ibgp router when receiving prefix returns (neighbor who sent the prefix) prefix with community

I know this is against the bgp rules

The neighbor will not accept this prefix that he sends itself

why? (may be used allowas-in)
I don’t need the prefix inject in RIB, only in the bgp table.

In 1.4 there is allowas-in:

https://docs.vyos.io/en/latest/configuration/protocols/bgp.html#cfgcmd-set-protocols-bgp-neighbor-address-interface-address-family-ipv4-unicast-ipv6-unicast-allowas-in-number-number

1.3:

set protocols bgp neighbor <address|interface> address-family <ipv4-unicast|ipv6-unicast> allowas-in number

1.4:

set protocols bgp neighbor <address|interface> address-family <ipv4-unicast|ipv6-unicast> allowas-in number

This cannot be implemented in ibgp and ebgp, as it violates bgp rules ?
that’s why I’m asking, is it possible to disable the bgp rule somehow?
