Make priority limit line dynamic on prioritization views

I would like to specify the metrics that automatically set the priority limit line on the prioritization view.

For example, if I know that my estimate limit for a list of records is 100d, I would like the priority line to dynamically set/adjust based upon the estimate total of the records in the list.

Another example could be basing the limit on product value scores. I want everything with a score of 50 or higher to be on above my priority limit line.
