[Question] How to specify different formats for multiple exports?

I'm trying to setup `microbundle` to provide separate exports for several modules my package is exporting, like this:
```json
{
"name": "x",
"type": "module",
"version": "10.0",
"author": "y",
"license": "MIT",
"devDependencies": {
"microbundle": "^0.15.0",
"np": "^7.6.1",
"typescript": "^4.6.4"
},
"dependencies": {},
"scripts": {
"prepare": "microbundle ./src/one.ts ./src/two.ts"
},
"exports": {
"one": "./dist/one.modern.js",
"two": "./dist/two.modern.js"
},
"files": [
"dist"
],
"types": "dist/index.d.ts"
}
```

However, I don't know how to specify different export formats for each one of my exports.

The documentations provides either this example, which shows how to proceed when doing "single" exports:
```json
"exports": {
"require": "./dist/foo.cjs",
"default": "./dist/foo.modern.js"
},
```
or this example, which shows an example of multiple exports, but in a single format:
```json
"exports": {
".": "./dist/foo.modern.mjs",
"./lite": "./dist/lite.modern.mjs",
"./full": "./dist/full.modern.mjs"
},
```

How could I specify multiple formats like in the 1st example, while still specifying multiple named exports like in the 2nd example?
