HELP! I have a quick action on an Account record which create a Case and adds the Case to a queue..

So here it goes, I have a quick action on my Account object that creates a Case and Assigns the Case to a Queue (which is a bigger bucket with all Case Types), which works fine. 

I am trying to create a FLOW that will then take one subtype from the above and will assign the Case not to a Queue BUT to the person who had triggered off the Case creation from the Account using the quick action. 

Any ideas how I can create this ?

Thanks

Any help appreciated.  Thanks
