Google Analytics - How to push custom dimensions before page view?

[ronenteva]

const {dataLayer} = useScriptGoogleAnalytics();
dataLayer.push({content_group: 'shirts'})

If I understand correctly, the content_group will be sent with the next pageview.
What's the correct way of setting custom dimensions?

Hi, to confirm are you trying to do something like this?

const { proxy } = useScriptGoogleAnalytics();

proxy.gtag('config', 'reset')
proxy.gtag('config', 'UA-XXXXXXX-1', { 'content_group': 'shirts' });

Yes, thank you

No problem, ideally you'd be able to do this in the registry signature.

Let me know if you have any issues with it.

Oh sorry, I didn't realize that's an actual solution.

Is there really a gtag('config', 'reset') that I'm not aware of?
Won't this send two pageviews, one before the reset and one after?
