There is currently no way to set a different default. Please note that when you edit the glossary from the Biblical Terms tool two things happen. 1) the entry gets created with the \p marker and 2) the entries get reordered according to the alphabetic listing of the language settings.
I would recommend not worrying about the markers or order until you have finished working with the Glossary and then at the end you can either change the markers or reorder as needed. In fact, you might want to change your \li2 to be \p during the process of preparing the Glossary.
