Importing streaming history from more than one account

I have two Spotify accounts, an old one and a new one. I wasn’t able to log in to my old account so i created a new one but the listening history is only from 3 years ago. I was able to finally log in to my old account but i already imported my history from my new account with plus. It would be great if we could merge the two accounts or import music history from more than one account and align them.
