Connected Alteryx and Marketo, but cannot see entire Marketo database, only lead records by static lists (lead ID). How can I see entire database?

For some reason, I cannot access all lead records in my Marketo database using Alteryx. I only see options to pull records by static lists, however, there isn't currently a static list that contains all my database users, and if I did, it wouldn't be dynamic.

Are there workarounds for this besides maintaining a static list of my database utilizing daily batch campaigns to add new people to the list?

Thanks
