Hey @jj41
From what I understand, the easiest way would be to create a custom event involving just the singular Page View event with the WHERE clause on the ‘Page Slug’ event property for all the values you want to filter on. There isn’t a direct way of saving a custom where filter afaik.
So Page View event WHERE ‘Page Slug’ = {‘apple’, ‘orange’, ‘banana’, ‘mango’, ‘watermelon’,etc} and naming this custom event something like “Page View - Filtered on <specific> Page Slug “. You can then use this custom event in your charts.
Another way would be trying to incorporate a saved user segment which contains your filter definition on the Page View event depending on how well it suits your analysis.
Let me know if I have interpreted your use case correctly. Hope this helps.
I also would benefit from being able to save a property filter. In my case there are a high number of known identifiers that I want to exclude from a property, across many charts.
The best I can currently do is “Copy Selected” on a filter from one chart and attempt to paste into another chart’s filter (this also isn’t supported well). But this process breaks when a new known identifier is introduced and I have to update every chart to exclude the new known identifier.
I see there is a feature called “Block Filter” that accomplishes this, but in my case I am still interested in tracking the data in other charts. I don’t want to completely block it.
