Is there a way to create Running Total using Beast Mode?

Hi,

I'm building a table card and I would like to create a column that performs a cumulative sum, like the following:

| Week | Amount | Running Total

| 1 | 100 | 100 |

| 2 | 50 | 150 |

I tried to do this using SQL Dataflow, it works fine. However, I want to be able to add filters that modifies the Running Total and thus, the approach that I used with SQL doesn't help me much (since it performs the sum of the whole dataset row by row).

Any light on this would be much appreciated

Thanks
