Limit Access to individual content blocks

[KarlDD]

Hello forum,

I having been searching the internet for the last 2 hours and haven't found a way to restrict the access to certain contents blocks to certain users, e.g. I have a page that has 5 content blocks, but 4 of them contain information I want to restrict to admin's only.

Is this already a feature? If not I think it would be a very helpful feature to have built in to CMSMS

Something like:
{content block="content_2" restrict="Admin"}

or multiple users can have access

{content block="content_2" restrict="Admin, Designer"}
