Point Rates Stats needed in Fangraphs

One more thought on this thread: currently, when you look at free agents or the sortable stats, there doesn’t appear to be a way to do a custom date split. There are drop-down defaults to specific months, Last 7 Days, Last 14 Days, etc. . . but no way to say look at the first half or second half of a season (or put in a custom range, ideally). What’s curious is that when you just go to Fangraph’s leaderboards, there are splits for 1st half and 2nd half at least, but that option isn’t available on the ON pages. I’d love to be able to do that because it’d be great to be able to identify which players had good (or bad) second halves, etc. Thanks.
