I would like the ability to create a new analysis workspace summary metric that is a formula (at first just divide, multiply, add or subtract) of two existing summary metrics. This is useful when there is no easy way to create a calculated metric due to different time frame needs, etc.
For example, if you have a summary metric for Daily Average of Unique Visitors and you want to divide it by the Weekly Average of Unique Visitors, it can be difficult. But if you had both as summary metrics (based upon underlying data tables), you could divide the two resulting summary metrics to make a new summary metric that is Average Daily Unique Visitors / Average Weekly Unique Visitors.
