Adding custom bullets

Hello everyone. In my courses I add custom bullets by adding small images that represent them, yet I am curious if there is a way to create a custom bullet like in Word when you press the dropdown menu next to the bullets button.

I saw that same dropdown arrow in Storyline 2, but I did not see the same options as in Word. Is there a way to do this? So that I do not drag and drop the images and align them every time I need a bullet?

Hope there is a way. It would save some time.

Thanks guys
