Variable global from querystring link to another dashboard

Hi all!
I would like to know if exist a global variable (catch all) 'cause my need is to create a link to another dashboad from a panel graph passing all the active variable present into URL on the page?

Example my URL now is:

I’m linking from a panel another dashboard
but… exist a global one for the parameters? Or I’ve to rewrite one by one?

Thanks Alen
