sync listbox filter scrollbar position

One of our customer is asking for this.

They have 2 or more listbox filters and each of them is added to text area in multiple pages and all of them refer to the same table & column and share the same filter scheme, so changes to any of them apply to all others.

However, if the number of items in the listbox is too many and the vertical scroll bar show up on each listbox filters, selecting items after scrolling down on one filter are not visible to other filters due to the position of scroll bar is not synced.

They want the scroll bars to be synced automatically to show the selected filter items.

See attached screenshot.
