Hi theavspecialist,
You need to create the Yes/No fields in the Customer table first, then you can edit your screen to delete the current Yes/No field you're using and select the field which you just added to your table. Then edit your CSV file to include this column as well, and enter the word Yes for all rows with records. The default value in Method is No, so your current customers/leads in Method will have a value of No.
Again, as stated above, you would need to create the Yes/No fields in the Customer table first. These fields will all be different fields, not linked. In regard to sending emails to the appropriate contacts in the future, we are implementing Tags into Method so it will be easier to filter and select contacts. However, it may not be the best route depending on how you want it to work. I would suggest speaking with an in-house Consultants or one of our Method Solution Providers to scope out your project, specifically the part regarding emailing certain people, to figure out the best route to take.
Let me know if you're interested in speaking with an in-house Consultant.
