WooCommerce Membership plugin customization

Hi, I need someone to do some customization for this WooCommerce Membership plugin so that users who already spent $150 to $1000 on the store will automatically assigned to a particular Membership Plan. Example: When user total spending if from $A to $B, they will be automatically assigned to Plan A. Total Spent $150 - $1000 ------> Auto assign to Plan A Total Spent $1001 - $5000 ---------> Auto assign/upgrade to Plan B Plugin link: [login to view URL] Custom Function needed: 1. Automatically detect any users with total spending of over $150 and auto assign them to the Membership Plan that I can set. 2. I can edit the total spending value range amount. 3. I can edit the plan the users will be assigned for each value range. 4. (Optional) Woocommerce send out Congratulation email when users been auto upgrade. Implementation: 1. It's ok if the customization being done via code snippets, with indication where to edit if I want to make changes on the range values & plans. 2. (Optional) It would be better if you can the settings UI/Option page/ACF Option to make the value changes easier for no-code users. Thank you!
