Writers want to see Xopus <Simple list> element directly from Insert icon

We are using the Xopus Editor for DITA document. Writers want to access the <Simple list> element directly from the Insert icon on the Xopus toolbar because it is used very often. Currently the <Simple list> element is embedded within the Insert icon list. On clicking the Insert icon, user then selects More Topic, then must scroll down towards the bottom of the element list.

When clicking the Insert icon the top section shows Insert Ordered List, Insert Section, Insert Unordered List, this is where the Writers would like to see the <Simple list> element. I just wonder how we can move the exiting menu item position in the Insert Icon drop list. Thanks.
