In our company, we've recently had a discussion about the usage of the verb amend in the context of a screen in our software user interface, where a button reads amend set (meaning add something to this set or modify this set). We're mostly non-native English speakers and this word seemed a bit exotic. Is it commonly used in this context?
From a non-native English speaker perspective, I'd prefer modify set. Our target audience is native (British) English speaking, though.
