Email/Notification for "forgotten" status change after a certain time?

Hello

Is there a way to trigger an event, after a certain time in a defined status?
The email on status change works fine and there are "Delay for tickets", which can be configured depending the days the ticket ist open.

But is there a way how to remind e.g. the requestor, that e.g. a specific state has been reached, but it didn't continue?
E.g. the requestor opens a ticket, the responsible process the ticket and provides the solution and sets the state "solution provided", where the requestor gets an email, but he "forget" to continue and switch to "solution accepted" (or reopen) and it remains in the last state. Now it would be good to send a reminder after the ticket remained e.g. 2 days in that state, so that his ticket is still waiting to be processed.

Or is there a way that if the ticket reached a certain state, to automatically close after e.g. 10 days?

Regards
