Add a feature to Sendy Autoresponder Script

Part 1: Need to modify a Sendy autoresponder script to add an option to only send email if recipient is not on a specified list. So lets say I have 1 list with leads, where I want to promote 5 products and I have 5 more lists that contain buyers for each product respectively. I would like to be able to set up autoresponder for my leads lists so that before each promo email for a product is sent to a subscriber, there is a check if that subscriber is on a buyers list that I specified and if they are then I dont send them a promo email, instead I advance them to next email in sequence. This way I can avoid sending a promo email to someone if they are on my buyers list for that product. To reiterate, when setting up autoresponder drip sequence I need to have an option to only send if recipient is not a list that I have specified. I need to be able to specify which list with option to pick any list from all lists that exist in the account. So for example if I have 5 emails in autoresponder sequence, I would like to be able to have email #2 check if a recipient exists on a list that I specified, and send the email if they do not. If the recipient is on the list than the email #2 is skipped and subscriber is advanced to next email in sequence which is #3. If i set up #3 to do a check then same procedure would be repeated and if recipient is on a list specified, than email 3 would be skipped and subscriber would be advanced to email #4 and so on. Part 2: I need to be able to setup a point in autoresponder sequence that moves the subscriber to the 2nd email in the sequence. This would keep looping the sequence, only skipping the welcome email. For example if i have a sequence of 15 emails, I need to have an option to move the subscriber back to the 2nd email in sequence once they reach the 15th email. I attached Sendy script and also an addon script that compares two lists and can exclude subscribers from one list from being sent to a campaign in another list. This may be useful when programming the feature that checks if a recipient is on a specific list. Also it kind of shows how this should look and be implemented.
