AFAIK history in bash is implemented such that each bash instance

exits it updates history file.
If there are multiple shells running together then commands entered in
one can't be accessed using history command from other shells.
I am looking for a feature where if a user has multiple shells and on
a special keystroke / command all shells get a common history which is
sum of all histories.
Does such a feature exist in bash or any other shell?
Can such a feature be implemented without changing the shell's code?
PROMPT_COMMAND='history -a; history -c; history -r'
