Time Filter with no start or end date

Is there a way to make it so there is not set value for a date filter. As in when I am loading under some conditions I want it to be infinite with no start time or end time (basically as if the date filter was not there). I tried sending parameter “dateFilter.start=undefined/dateFilter.end=undefined” But that didn’t work, as the date filter was over-ridden by the most recent saved date filter, which isn’t desired.

@austen might be worth checking out this thread on creating custom date filters. You will have to try a few things to see if the JS library supports what you want.
