Random categorized questions - using a different widget for category selection

Hello,

When using random categorized questions, you need to select a category for the questions to be picked from. Right now, it seems that only the 'auto complete' widget is available for this selection. Which means that if I have terms with the same name in several taxonomies (or in a single taxonomy but different hierarchy branches), the user can't differentiate them.

I think being able to switch to another widget is mandatory - one of the other widget that is available in "Manage fields" (Select List for instance or even better would be the Hierarchichal Select from this module : https://www.drupal.org/project/hierarchical_select)

Unless this is already possible?

Thanks
