Initializing filter state on when visual is hidden on page load

I have created a custom date slicer visual. We are hiding/unhiding it with bookmarks in our report. Because of this the visual is destroyed when it is hidden and re-rendered when unhidden.

I can use persistProperties to save the selected date range and retrieve it when the visual is unhidden.  My issue is that on first load of the report I would like the date slicer to defualt to YTD calculation. How can I distinguish between the frist time the visual is rendered and subsequent renders after the visual is hidden and unhidden?
