Interspire Email Marketer Addon to Suppress Emails

Hi, Hey, How much would it be for a suppression list feature per email campaign? So e.g. when setting up an email campaign there is a box to upload a suppression list for just that 1 email campaign. So it suppresses those emails but only that one email campaign. Future email campaigns might not have a suppression list or they may do but its different. This would be an addon we can disable enable like other addons built for Interspire email marketer. You need to have experience with Interspire email marketer if you are going to bid on this project. Thanks.
