Link rel=canonical: is there any way to insert in template?

[ipbfuck]

Hi! I've try to insert with live metatag editor, but this put only "meta name" and not "link rel" tag.

in single page isn't possible, and i cannot see other setting to enable.

<link rel="canonical" href="//***" />

 

is there any way for this? is one of the most important SEO setting :/

 

regards...
