@eugenekasimov — This may need to be a more considerable effort. Please refer to the issue: #1748, initially raised by @nicklepine.

If your solution here is used until this greater effort is achieved, I suggest having a "Product meta" block and having the settings look like such.

Ps: You could combine your efforts with your other PR (#1979) if you use my suggestion above.
