I have a scenario where I have layers of data. Each 'host' has multiple 'locations'. Each location has 'sessions'. I am able to rollup all data from sessions at the location level, but now I want to rollup the locations to the 'host' level. However, when I try to select the data, a rollup is not allowed. In the meantime, I can do this with formulas, but figured this could be helpful for others.
