Extend custom fields configuration to ToDos Merged

Would be very helpful if we could define custom fields for ToDos, similar to what is possible for other elements. For instance, we have various meetings where we create ToDos in Aha, and then want to review those ToDos at the next meeting. It would be very helpful if we could create a custom field to record at which meeting the ToDo was created so we can easily pull-up all the ToDos for that particular meeting the next time. We tried doing this by creating minutes for the meeting in Notes and then creating the ToDos from those Notes, but sometimes we don't create Notes and if we do, we need to go back through all past Notes to find all past ToDos.
