Recache a single site node

Is it possible to tell IG to recache a specific site node from the CMS tool?

It should work to add refresh=true&isRecacheCall=true to the query string of the URL to the site node, and maybe that is enough, but it would be nice to have a button or link that explicitly did this (on the content cover for example).

Seems like isRecacheCall does nothing, but refresh=true works.

One can also note that the admin manual says this about the Default Page Cache Key:

The default key is: siteNodeId_languageId_contentId_userAgent_queryString

But in the site node cover, one should put $ before every part of the key, for example:
$siteNodeId_$languageId
