Hello Sandaruwan
yes you can if any user change the company from the drop-down
then there is one JS method called setCompanies() in web/static/src/js/core/session.js
you can inherit that method and include your code

setCompanies: function (main_company_id, company_ids) {
var hash = $.bbq.getState()
hash.cids = company_ids.sort(function(a, b) {
if (a === main_company_id) {
return -1;
} else if (b === main_company_id) {
return 1;
} else {
return a - b;
}
}).join(',');
utils.set_cookie('cids', hash.cids || String(main_company_id));
$.bbq.pushState({'cids': hash.cids}, 0);
####write your code here####
location.reload();
},
