How to include bulleted list within a checklist?

I have a task. Within the task is a checklist of items. I want to include bulleted lists within the checklist, but when I try to assign the bullet style to the text within the checklist, it changes the entire checklist to bullet. Is this possible and if so, how?

If I press the bullet button again, the checklist turns into a single bullet entry:

thanks for your help!
