ranger chain commands in config

I am using ranger as my terminal file manager and now that I understand the basics, I wanted to get a bit deeper into customizing the rc for my purposes. One thing I like to do is to map a command to a keybind that copies a template into the current folder and then starts the rename_append command, (usually called with keybind a) on the file. Here is an example: map NS shell cp ~/.templates/bash.sh . ; rename_append The problem is, that no matter how I call the command, it does copy the template in my current directory, but then doesn't start the rename-process. When I quit ranger, the errormessage says that rename_append wasn't found, but in the ranger-config, the same command is used to rename files before the appendix. My theory is that, since I am using shell, the command tries to find rename_append in my programs. I don't know how to chain commands in my ranger-config where one is a shell-command and the next one isn't. Currently I have to use a second keybind after the first and I would like to only use one and automatically go into renaming-mode after copying the file. I hope, my problem is understandable.
