Line Items in SuiteCRM 7.9.2

Hi - I have a read a few forum details about how to add ability to add Line Items to a new module.

The older versions involved working directly in some php and js files. Is this still the case in this version ? Have things changed to the degree that we can use the module builder to handle this element?

Basically I want to add a new module Called “Foo” and then one called “Bar”. The Bar module would be a line item module similar to the quotation module. Difference is that I want to add line items which allows me to select records of “Foo” for each line item.

Is this possible with the Module Builder? What would the steps be involved?

Thank you in advance.
