Calling gtag('consent'...) before configure is not possible

[grantmcdade]

gtag.js allows you to call gtag('consent', 'default', ...) and then later on gtag('consent', 'update', ...) to prevent tracking and cookies before the user has a chance to consent to them. I can't find a way to do this and if I only add and initialise the script after cookie consent is granted, none of the initial pageview data is sent.

Is there a way to do this currently? (My goal is to not save any cookies until allowed but still send the initial pageview, even though it is sent later)
