Making the progress bar (baattery= dependant on a different input that status colum

Has anyone found a work around for this yet? We are the same, we use percentages% for our progress, not stages that work as columns. Example: A group may be “Create Training Docs” and the tasks are the document names. We have a manual column for “Progress %” and we update the % as we progress through creating each document. It would be nice to see a battery or gauge based on input %'s as that’s more visual than a column with 10% or 90%.
