dual CA configuration for EAP-TLS

[Leandro]

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.
