Can I delay GTM firing when tracking through the Google and Youtube App?

[formuladoctor]

I have Google tag tracking set up using the automated integration of the Google & Youtube Shopify app. 

I want to delay firing of the Google tag because it is slowing down my page loading. This is how the tag appears in my Google Tag Manager. Of note, this tag is not associated with my Tag Manager Account (as shown to the left of "Google Tags").

Clicking through to the tag, there is no option to delay firing. 

Does anyone know how to delay firing using the GTM interface or by editing code on my Shopify site (Dawn theme) to delay when the Google & Youtube app loads? 

As another possible solution, does anyone know how to associate the automated Google Tag with my GTM Account? When clicking into the GTM account, there are options to customize the code and create trigger conditions -- but these options are not available when using the automatically configured tag.
