Use Variables/Values set by e-commerce Tracking

Hi there,

how can i use the values which i set in e-commerce Tracking Code (https://matomo.org/faq/reports/advanced-manually-tracking-ecommerce-actions-in-matomo/#tracking-orders-to-matomo-required) within other Matomo Tag Manager Tags?

For example “grandTotal”…

Is this possible or do i have to set these values again in a set of datalayer variables?

Thanks in advance!
