Using Randomize within macros

Hello - I have been having fun with macros, but I have not figured out if it is possible to get the macro to ‘randomize’ seeds (when clicking the dice button. I have been tried attaching automation scalar, but that doesn’t seem to work. To be honest I am still not really sure how to use the parameters properly, which I feel is the secret to unlocking macros!

I would love to learn if there is a random integer generator but for now what I do is add a scalar to the macro parameters and assign a range of 0-32768. Not very elegant, but better than having to go into the macro and then into your device and hitting “new/randomize” for the seed.
In fact that’s why I’m on the forum right now. Trying to discover a random integer generator device.
