We have a requirement where the SLA timer is needed on the home grid of a case. Our current solution is for a Flow to iterate through open cases every 2 minutes, calculate their response due time and then update the case record but this smashing through our flow runs and is very slow. Ideally I would like to write some JS to run and calculate the response times when the grid is refreshed however there is no way I know to place procedurally generated text on a column. Below is how the system solution currently looks, ideally I would like it to look similar, minus the flow in the backend.
Any ideas appreciated.
