dual CA configuration for EAP-TLS

Hello FR users: I need to create a new CA-clientes certs batch but also need to keep current working. On a third party AAA server I used to make an append to the current CA cert like: cat newCAcert.crt >> currentCAcert.crt then restart service and server was able to work with both CA certs. Is it possible to achieve the same with FR ? Regards, Leandro.
