Single or Multiple IDs for same value but in different states/questions
I have a lookup value "Unread". It is used here:
Mail can be read or unread. (So i have ID 10 = read and ID 11 = unread). Now in the UI I have display filters where i can sort message by predefined filters, one of these is 'Unread' So the question is: Are the IDs in both cases going to be 11 or do i create two separate values for Unread - one for the message state and one for the display sort?  

The use of this data is 2 folds:  
1) Reference its main action based on the FK lookup ID  
2) Reporting: If i want to see how many users sorted using Unread filter for Unread mail, in which case can i get that number easily - by using two IDs (one for each question (message state and display sort) or one ID only?
