Speed up entering collections by adding a check box to be able to select multiple cards at once or the entire set

Need to speed up adding cards to personal collections. For example I want to add an entire set (like all 550 cards of a set) to my collection in one shot and then remove those I don't. Currently adding one at a time is too long when want to enter thousands of cards into sportscardsPRO...... place a check box beside each card so I can add multiple cards to my collection all at once and in the same folder. A select all check box would be top notch.
