Picking up a call but still performing it with phone and connected earbuds

I am often using my phone with my Bluetooth earbuds listening to music. I also do my calls with the buds connected to my phone. With my old vivoactive 4 I could use the watch to see who calls and pick the call up - but still performing it via phone and connected buds.

But with the venu 2 plus now the call is automatically transferred to the watch and I haven't found a way to avoid this issue! For sure, the calling feature of this watch is a big progress. But in most of the cases I only want to use the watch (eg. when the smartphone is in my pocket) for looking who calls and picking up the call. But then I absolutely want to do the call via phone and earbuds. 

Is there a way to prevent the Venu 2 from overtaking the call? 

Thank you a lot for your answer!
