Import MXU file including SSL option - how to do it?

Hi Mobotix community,
Frequently we need to add manually 10 or more camera’s by customers (search is disable by firewall).
W’d like to do it with MXU import . That’s working fine for HTTP camera’s but not for HTTPS / SSL enable camera’s.
We’ve used this instruction:
but we don’t see how to enable the SSL option.

Do you have any idea’s. Thank you.
