MacOS Pinyin input method currency symbol

From what I gathered, it seems that the Pinyin simplified input method hardcoded that Shift+4 inputs a Yuan symbol ¥, and I don't see a way to change it to other currency symbols. I would like it to just input $ instead, since it is used as important operators in programming etc. Changing the system language, region and currency designation doesn't work. Is there a known way to do this, or do I have to install a third-party input method?
