Is it possible to merge youtube accounts?

Question

Google

With the introduction of any innovations, YouTube creates a new account for me. Here again recently. Now I have 4 YouTube accounts. And if earlier he just created an account, now he insists on using a new one - every time you start the browser, YouTube switches me to a new account.
For a long time of use, a lot of subscriptions and bookmarks have accumulated, is it possible to somehow transfer all this to a new account automatically or somehow? Doing it manually can be stressful.
I am ready to put up with the fact that the account will not be anonymous, the main thing is that Google has already lagged behind me.

Answer 1

What is the creation of a new account?
I have been using the same one for many years, and only recently, under the onslaught of Google, I connected Google+ to it. But at the same time, it's still the same account, with all the subscriptions, playlists, etc...
Maybe the original account is corporate? Not sure about the ability to use Google+ on it. In general, you need to try to turn on this very Google+ on the old account, because Google, as far as I understand, has already firmly tied youtube to its social network.
Do you have such a list?
