User to vote once per day for 1 post type

We purchased the pro version of the plugin and I was curious if the following is possible — We have a custom post type “charity” and would like it so that users can vote for 1 charity per day. Currently, the settings only allow us to limit the number of votes to 1 per charity per day, but not the total number of votes per day.

After a quick review of the code, I suspect I could make some alterations to make this work but wanted to ask if this is something that is already documented somewhere.
