Secondary Title?

Hi, how are you all doing?

I'm wondering if there is a way to put a Secondary Title after the main Title, (see attachment). For WordPress site.

I have searched many times, found many plugins, but is there a way to insert it without plugins?

Thanks!

That feature used to exist in Gutenberg editor but for some reason they removed it.

Here is a workaround that worked for me (Check Prashant Singh's reply) :
