Countdown Timer for Response SLA

We would like to find a way for getting some sort of response timer in Asana.

Example: We need approvals for a design on 1 task, we tag the the person and we would like to have a simple way of requesting a response from them with a timer.

Hi @Eric_Carr, what is the difference between what you are requesting and just adding a due date/time to the task?

Hey Todd, thanks for the response.

How my team operates internally is a little unique in the sense that we go through several small approvals for just 1 task. It would be much easier to just set timers for specific tagged collaborators rather than creating several small sub-tasks. I personally think we should be using a DAM but I wanted to see if there was a simple integration that could solve our problem today.
