Define a mandatory parameter on a wildcard in ASM

Hi team,

I have to define an ASM policy into which I want to use a mandatory parameter for every URL.

Let me explain a little bit more :

Now, I have a parameter on a explicit URL defined into the "Flow URL". I enabled mandatory function, but this website isn't static so everyday I'll have new URL.

So in order to save my time, I'd like to define this mandatory parameter on a wildcard URL.

I'm running 11.4.1 HF2.

Thanks in advance.
