beast mode using window function as a filter

Hello,

I have a beast mode that's very important to calculate the summary number correctly. I can't find any alternative to this. However, it is using a window function and I'm wondering why it won't appear if I tried to add it as a filter in the card or dashboard. I can add it in the quick filters pane of the card, but it's important to be able to find it in the dashboard filter.
