On Cisco Routers/Switches there is a so called command alias configuration node available.
e.g.
alias exec tt copy running-config tftp://172.16.20.200/CONFIGS/BR1.wueI.xxxxx.net-confg
Will create a new custom command "tt" at global configuration level which performs the "copy running-config tftp://172.16.20.200/CONFIGS/BR1.wueI.xxxxx.net-confg" command. Those alias commands could be stored in /etc/bash.bashrc where every system user is able to make use of them.
set system alias command tt "copy file running://config/config.boot to tftp://172.16.20.200/CONFIGS/BR1.wueI.xxxxx.net-confg"
results in:
$ /etc/bash.bashrc alias tt="copy file running://config/config.boot to tftp://172.16.20.200/CONFIGS/BR1.wueI.xxxxx.net-confg"
