How can I transport a note from one ticket to another ticket within same contact?

How can I transport a note from one ticket to another ticket within same contact?

Hey guys, 
Is it possible (and if so - how to do it) to have a field in the ticket where once data are entered - the very same data will be available for other agents in different tickets made by the same contact?

So the scenario is that when one agent leaves a note in the ticket in this column when editing the ticket:
place for some information
another Agent when answering to another ticket from the same Contact will see the information. And that information will be visible for each ticket of this contact.

This is a much needed feature to leave a short note about the contact that will always be visible for each agent. 
I'm aware of the workaround with CRM notes - but that's not working as typing the info there is time consuming + it's not obvious if the information is there or not without checking it in the CRM tab.

Please advise how this can be solved.
Thanks!
