Payment Plan Suite for WooCommerce

Hi, we’re using your plugin to set installments as a unique payment method. We are selling customized tours so each product is also unique and has a group of customers associated to. The last installment date and amount may change, so we need to edit it and we would like to do it in the Plan and the each user could see their plan changed, and not to have to edit it individually by each customer. Could it be possible?
