How to build multiple pages (without router, resp. using vite-ssg/single-page for each)

[derMart]

Hey, I need to build multiple separate outputs using the vite-ssg/single-page rendering.
Config is like this:

import { resolve } from 'path';
import type { UserConfig } from 'vite';
import vue from '@vitejs/plugin-vue';

// https://vitejs.dev/config/
export default {
  plugins: [vue()],
  ssgOptions: {
    script: 'async',
    formatting: 'prettify'
  },
  build: {
    rollupOptions: {
      input: {
        main: resolve(__dirname, 'index.html'),
        login: resolve(__dirname, 'login/index.html'),
      },
    },
  },
} as UserConfig;

Both typescript files included in the htmls are generating their app using:

import { ViteSSG } from 'vite-ssg/single-page';
import App from './App.vue';
export const createApp = ViteSSG(
  App
);

But only the main input is prerendered:

> frontend@0.0.0 build
> vue-tsc -b && vite-ssg build

Is this a bug or how to tell vite-ssg to prerender all inputs?
