Use aliases as custom commands in terminator

I am using a terminator layout to start multiple terminals, and would like to call an alias at each terminal start which is defined in my .bash_aliases (called by both .bashrc and .profile). Terminator unfortunately doesn't know about those aliases when starting the terminals. How can I fix that? I start terminator with this command: terminator -l my_layout -f EDIT: As a temporary solution, I ssh -A -YC into myself and then run the alias. All this as a custom command.
