That might be impossible, as there is no way to tell from the server side if the filters have changed or not, or if this is the first request from this session, that is the problem. The auto populate can be distinguished, as it sends an additional parameter, but this is more problematic.
The only way I could resolve this, is to check if the date filter has the current date, to assume it has not been changed – but then if the user selects the current date, then it will have no effect. I am honestly not sure if there is any way around this unfortunately. Let me know if you prefer that solution.
