Other options for scrolling in a large queue

When there are more than 9 cows in the queue, it is hard to scroll through them without accidently completing the chore.  Many times when moving cows or sorting them for tasks like trimming, farms are putting the IDs in the queue to indicate they have seen her and she is in the group of ahead of them.  With paper, farms were putting "dots" by the IDs to indicate the same thing.  When the cow exits the pen, they would cross her off the paper or with Bovisync click to finish the chore.  Is there a way to either make scrolling through the queue easier so we don't accidently clear a chore or maybe make the first click on a cow, just highlight her ID in the chore list and then the second click clear the chore?
