This question comes up all the time.

Q: Does Amplitude support passing in a list of values into a property filter?

A: YES!   

Just separate the values with commas and be sure to “Select All” after you copy &  into Amplitude.
Side note: make sure to trim any whitespaces before and after the values before pasting into Amplitude to ensure they’re valid property values.

Here’s the official documentation. 

Here’s a short video on how to set this up.
