How can I register multiple IMSI with magma MME docker?

[lgs96]

Hi, I'm currently working with magma mme, but find it is hard to register multiple IMSI with provided docker env.

In docker-compose.yml of docker-compose/magma-mme-demo, I could register IMSI with following scripts

environment:
TZ: Europe/Paris
REALM: openairinterface.org
HSS_FQDN: hss.openairinterface.org
PREFIX: /openair-hss/etc
cassandra_Server_IP: 192.168.68.130
OP_KEY: 1006020f0a478bf6b699f15c062e42b3
LTE_K: fec86ba6eb707ed08905757b1bb44b8f
APN1: oai.ipv4
APN2: oai2.ipv4
FIRST_IMSI: "001010000000008"
NB_USERS: 30

I can register a single UE IMSI, but how can I register second, third, .. and additional IMSI?

Thanks in advance.
