How to sort the matrix ignoring hierarchy.

Hello, I have an issue with Power BI. I've created a matrix displaying key subjects on the row level and indicators (numerical a ) for these subjects, along with other values grouped by day in columns. My indicators have unique values for each key subject. However, when building the matrix, I was forced to place them at a different hierarchy level below. The problem is, I can't sort by any of these indicators. I want to sort, like in Spotfire, ignoring the hierarchy. Here, I can only filter my key subjects alphabetically. Do you know how I can work around this issue?
