GNU screen with bash init script

I am sure that there is an answer to the screen in this manual, but I cannot find it! I want the bash shell spawned by the GNU screen to be the source in the file in addition to the already running .bashrc.

I can’t put the call into a file in .bashrc because on our site .bashrc files are automatically restored at login.

Any ideas?

EDIT:

I created this little script (screen_bash.sh):

bash --rcfile ~/.screen_bashrc

Then added

shell $HOME/screen_bash.sh

In my .screenrc

The file ~ / .screen_bashrc was

<my_setup_stuff>
export SHELL=bash

SHELL = bash is required so that programs such as vim can run sub-shells correctly.
