When setting a TO-DO reminder on a ticket, it would be great if there were (in addition to the date picker) some quick pick relative dates (eg. tomorrow, in three days, in a week, in a fortnight, in a month)
The use case is that for many tickets, we are waiting on either the client or another party to take an action that will progress the ticket to resolution.
In such cases, we set the ticket to a ‘waiting’ type status and create a to-do reminder to make sure the ticket doesn’t get forgotten due to non-action by the other party.
The key is that we don’t want to see the ticket again until a) the customer/third party responds OR b) the reminder goes off prompting us to follow-up.
Setting the reminder quickly for a defined number of days would speed up this process (which can be oft repeated on a ticket).
