Ability to sign into multiple microsoft accounts on new launcher

On the old legacy launcher, you could add multiple different accounts which you could switch between quickly and easily. On the current launcher (the microsoft store launcher), there is no such option and every time you want to switch accounts, you have to log into the account which is much slower therefore, I suggests that you should be able to sign into and save multiple accounts on the new launcher.

Note: this is technically a bug but on the bug reporter, the bug has been tagged with intended behaviour so therefore I am suggesting it here rather than on the bug reporter.
