Lambda repeatable addGraphQLResolvers

Are the functions self.addGraphQLResolvers and self.addMultiParentGraphQLResolvers repeatable calls?

For instance if I have two different fields I want to resolve with a lambda, do I have to call them together like:

self.addGraphQLResolvers({
    "Author.bio": authorBio,
    "Character.bio": characterBio,
    "Human.bio": humanBio,
    "Droid.bio": droidBio
})

Or can I call them separetely like:

self.addGraphQLResolvers({
    "Author.bio": authorBio
})
self.addGraphQLResolvers({
    "Character.bio": characterBio
})
self.addGraphQLResolvers({
    "Human.bio": humanBio
})
self.addGraphQLResolvers({
    "Droid.bio": droidBio
})

Reason: We are trying to keep code manageable and want to split up the lambda file to the separete functions and compile several scripts into one in the CI/CD pipeline and then push it to Slash. I added a second resolver function and thought I could only call the addGraphQLResolvers method once. Can anyone expound on this without me wasting time trial and error.

you can call them separately, not a problem at all.
