Move to corresponding item in 2nd listbox when item in 1st listbox is selected

I'm trying to do this in App Designer 2019b (scroll function does not exist)

I have 2 listboxes LB1 and LB2. LB1 items are 'Ex1, Ex2, Ex3....' and LB2 items are 'Example-1, Example-2, Example-3....' In short, LB1 contains words and LB2 contains descriptions of those words.

What I would like to do:

When I scroll down to Ex150 in LB1 and select it, I would like the matching item 'Example-150' to be visible/selected in LB2.

I'm using the ValueChanged function for LB1 to highlight/select the matching items in LB2 but this works only in the first set of items.

Once I scroll down LB1 and select Ex150, LB2 does not scroll to Example-150 even though it is selected.

If I manually scroll down LB2, I can verify that Example-150 is indeed selected.

Since it is 2019b, I cannot use the 'scroll' function. And since it is in App Designer, I cannot get the ListboxTop property, it seems.

TIA for any suggestion!

@Joe Rustan - could you use a table instead to manage the two columns of short and long descriptions? Or must you use list boxes?

Will look into it, I'm not sure. I make quite a few calls to listboxValueChanged functions to trigger other routines, so the tables approach would have to handle these. Will keep you posted, thanks for the suggestion.
