Simple script to easy add env variables, or changing the path without having to always change the bash[rc,_profile,etc] file. Add these lines to your bash[rc,_profile,etc] file once and then just add files to the folder configured on the SOURCEABLE_DIR variable.

sourceable.sh

# Sourceables
SOURCEABLE_DIR=/home/erick/sourceable/
DIRS=($(ls $SOURCEABLE_DIR))

for dir in "${DIRS[@]}"; do
  if [[ "$dir" != *.ignore ]]
  then
    source "$SOURCEABLE_DIR$dir"
  fi
done
