Hi @alexander-held ,

I watched your pyhep tutorial recently, and was super enthusiastic by how streamlined this package is!

I started playing with it for my analysis, and I wanted to try a study where I wanted to apply some different filters for the individual samples as well as an analysis categorization to define a regions.

I can see where to modify the _filter class to implement an "&" the two filters if both the Region and Sample Filters are provided, but I was wondering, would it maybe be useful to submit a pull request in case others are interested in this functionality in the future? Or am I not correctly understanding how I should be using these Filters?

Thanks so much!

Best,
Nicole
