It's possible to set a custom target for capistrano, so instead of
cap production deploy
or
cap production my_custom:task
I can use
cap deploy
cap my_custom:task
For easy way you can create alias for command cap production
alias capp="cap production"
and after that you can use command how
capp deploy
capp my_custom:task
for run alias for your session you can set that into ~/.bashrc
