Customisation of cart and checkout summary block im wordpress woocommerce

hi, I need to modify the cart and checkout summary block of woocommerce in wordpress site. The price should show a list of product bundle which has files with prices of one time payment and some files like supscription which should show monthly price base. I am not using supsrciption plans on the site, also dont need to setup payment gateways because I dont sell at this moment, just collecting leads. Maybe the shipping class options could save the problem by adding unique classes to the different products. I already use a plugin to show up the prices (for example before price label "mtl" stands for monthly), but in the cart and checkout summary it dont loads the function of the current used plugin for custom price label. Some sites using sales funnel where you can for examle choose a smartphone with one time payment fee and in the bundle a monthly supscription package of the network provider. In the cart and checkout summary block this is separately listed. Screenshot examples are uploaded. The 2nd screen shows my site where the bundle already loads the custom price label but just for the main product.
