Advanced Random - Is there a way to delete probability table / clear an existing one ?

Hi,

Using the Advanced Random built-in plugin, I was wondering if there was a way to clear all values from a given probability tables to re-use it for other purposes or value sets. And also if there was a way to delete/destroy an already existing one.

So is there a way to :

- clear all values from a given table

- know the number of entries in a given table

- destroy a table

Thanks to everyone in advance.
