How to copy blockquote text easily in mobile browser?

Question

When we long tap in mobile/tablet browser then we get content selection option like copy whole page, copy selected text, share button, and search button

Picture copied from this thread.

So can I select full blockquote text(<blockquote>This is sample text</blockquote>) directly without going upper or below?

I know I can't add another context menu(callout) but I am looking some solution which copy full text of blockquote in first/default touch and not just single word.

Feel free to add another way to copy/share blockquote text easily, but I am looking for lightweight solution. I tried whatsapp and twitter solution, but it make my page lengthy, since I have multiple blockquote per page.
