Cost+: Advanced POS Discounts

We are planning to launch SALE for our customers at our physical store using Shopify POS. Not able to workout with the app where we had different % discounts based on order slab for various collections & this app does not fulfill this in Automatic Discount or by applying single code discount. Our staff member can not take separate orders collection wise where discount % & order value slabs differs. Collection 1 🏷 10% OFF on purchases above ₹10,000 🏷 15% OFF on purchases above ₹20,000 🏷 20% OFF on purchases above ₹25,000 Collection 2 🏷 10% OFF on purchases above ₹10,000 🏷 15% OFF on purchases above ₹50,000 We need automatic discount to be applied only on POS not on online store orders. Support Agent explained that this kind of situation not possible but a blanket % of discount for all required collection can be possible which is not fulfilling our requirement. Sorry but disappointed with the App's feature. Highly Disappointing App.
