Please add new section. When use Smart Home i have to make different usernames and passwords like username and password for Mqtt, Cloud service, add-ons, samba share, SSH, and many more otherwise I must write mqtt username mqtt password, mqtt port, mqtt host,
Beautiful and clean option is ADD NEW SECTION.
Example :

SMART HOME

user:myuser
pass:mypass

Section > MQTT

host:10.10.1.14
user:myuser
pass:mypass
port:1265

Section > Samba Share

user:myuser
pass:mypass

SSH

host: 10.10.1.12
user:myuser
pass:mypass
port:3456

IPCam

host:10.10.1.1
user: myuser
pass: mypass
