Sure thing! Looks like you’re trying to add “/from-somehost” to the page view paths of a host. In GA4, you can’t set filters like in UA, but you can pull the hostname and path to your exploration reports and tweak them how you like.

By the way, a lot of data gurus find GA/GA4 a bit restrictive, so they go one step further. They pull the data into BigQuery (BQ), analyze the raw data there or transform the data more (that’s what ETL stands for – Extract, Transform, Load). And then, they use more powerful tools to make dashboards and do some detailed analysis. Just a thought in case you need more flexibility!
