Too many items to be highlighted on a mobile app list view

I have a screen that the user can observe past transactions of the credit card. There can be 40-50 rows (on average) on the screen, scrollable downwards. I would like to offer one feature for some of the items on the list, and another feature for the remaining items. How should I highlight those items and do not over-stuff the screen. Coloring? Assigned tooltip sized icons on each row? Other suggestions are also more than welcome.
