A way to group values of a property together into a "bucket" of values?

Hi everyone! New to Amplitude here, so would really appreciate advice – and I’m looking forward to giving back to the community as I get more experienced :)

Is there a way to group values for a user or event property into a “bucket” that would be a singular value, either for that same property or for a new, different one?

E.g. Let’s say Device type as a user property has a lot of values, like iPhone 12, iPhone 13, Samsung Galaxy Pro, Android whatever (I don’t know the Android models haha). Can I bucket all these smartphone values into a new value called “Mobile”? Whether that is for the Device type user property, or a different separate one I could create? (Also, if this can be done, can it be done for event properties too?)

If this can be done, could you please share the steps to doing it? :) Thanks so much!
