Dear HubSpot Team

I kindly ask you for implementation of calculations on Line Items.

It can be very useful when API is in use.

Examples:

1. We can calculate Deal\_ID on Line Item as property. So you don`t need to search through associations. Using Update Date and Deal\_ID properties on line item, you can simply reach deal in one api call.

2. Default field on Line Items, calculated on the basis of field on Deal.

Best regards

+1 . Yes, being able to create a calculation field as a property of a Product or Line Item would be super helpful for managing complicated inventory.
