I thought instead of adding the same script twice, I’d handle which argument was empty and go with the one who wasn’t. But I just error out with “Missing token for argument”.  
Is there any way out of this, or is a copy of the code block the only way?

No, this is not possible.  
Ive tried so many ways.

Only way is to use Advanced Triggers (or the build in start-a-flow-cards) and pass the tag along as argument.
