You're already saving the values to the profile natively, which is going to be the simplest method of storing and retrieving data, by far.
If what you want is literally to just write both values to the same text file, there's nothing stopping you from doing so(you can use both tokens in a single line).
However, if you're looking to store and retrieve values to and from a text file, that's a whole lot more involved, especially if you want use arbitrary amounts of arbitrary-typed variables(and you would, instead of writing a custom format for literally every usage case).
You could look into ini libraries, if you want to keep it somewhat human-readable, or xml(which is natively supported in .NET), but any solution you pick would require at least an inline function to work(I'm not saying you couldn't put something together entirely out of actions and tokens, but that'd be a nightmare to build, let alone maintain).
