Tracking Rogue casts

Does anyone know if there is a way to see how many casts of Blunderbuss I used while I had the buff from the Outlaw Legendary bracers?

I made the below query that returns them back as individual bars pinned above the normal view but I would really just like to know the number without manual counting so I could tell how many casts were buffed.

0$Separate$#244F4B$casts$-1$0.0.0.Any$0.0.0.Any$true$0.0.0.Any$true$202895$and$auras-gained$-1$0.0.0.Any$0.0.0.Any$true$0.0.0.Any$true$209423$true$true

Here is a link to one of my logs where I’ve applied that pin

Try to change type of the pin: Decorator -> Filter - it will display only casts with this buff.

That worked perfectly. I thought I had tried that before and it did so what
I wanted. Thank you!
