You can already do that
I suspect you enabled the 'strip tags' parameter.
Now, you just have to let the system know that you want to keep the ul and li tags ('keep tags' parameter).

Perfect, that means all html formatting you have done in the 'miscellaneous information' field of your contacts will show.

Note that this cannot work if you selected 'meta description', since the meta description is just plain text and does not allow for html tags.

Finally, if you don't get bullet points, it may just be because there is CSS that removes them. 

Using your browser (right-click -> inspect usually), you can tell if you have ul and li tags and if CSS has been applied to the text.

It then is just a matter of adding your own CSS to make the bullet points appear.

If you don't know what to do, just give me the URL and I will let you know what to do.
