Do we get the post purchase event in custom Pixel?

I see that when someone purchase anything from my store we get a checkout complete event in custom pixel. But in my store if we have post purchase then when some one purchase from the post purchase flow then that purchase event we don’t get in the custom pixel.

Can any body help me how to get that event without using the post purchase script in the checkout settings.

Note: - Is it in the road map of custom pixel ?

are you talking about the ./account/orders/. order-status page? Or you mean an upsell module on the confirmation page that causes a second order?

@zamartz I am talking about upsell module on the confirmation page that causes a second order. Like
