Dynamic or override layout META

Have the current meta on my NODE layout page.

<meta name="viewport" content="width=device-width, initial-scale=1.0, shrink-to-fit=no, maximum-scale=1.0">

Want to override on some CONTENT pages to allow zoom and increase scale

 <meta name="viewport" content="width=device-width, initial-scale=1.0, shrink-to-fit=no, maximum-scale=5.0, user-scalable=yes">

Suggestions? T

Suggestion:
Create a variable in your layout page, comma separated list of page names where you want increased zoom and scale.

Put your meta tags in a condition statement or embedded Node If statement.

Match on Header page request and a "contains" or not contains against your list of pages.

Nice, I will give this a shot. Thank you!
