Pro Forms: Bind date range to another field or two fields

On Flatpickr docs for the range plugin, there is a showcase which works so that when choosing range on either field sets the respective end on the other one. The config suggests that it is enough to bind the second field to the first.

But when using “Binding” on the first field with range and providing the second field’s ID, the second field (binded) gets the start date but the first one displays as a range.

So I would like it to be possible to work in one or both of the ways:

  1. Have two date fields. Select range in one of them and have the other get the other end of the range. Same way as it works in the docs.
  2. Have three date fields. First is a range picker with “Show Visual Calendar”. The other two are simple date pickers but in disabled state. Selecting a range in the first field, updates both fields with respective ends of range.
