Quoting Subscriptions with one Time costs

Quoting Subscriptions with one Time costs

Hello all, 
We sell a subscription SaaS service for which we provide one-time services for implementation and customization. 
Using CRM quotes i was able to create customized total fields to show the total one-time costs, monthly cost, total subscription cost, and total cost. 

However, CRM quotes doesn't support sending quotes to customers to accept or decline so we are moving to using books estimates with the integration to CRM but this customization doesn't seem to be available am I missing something?
