does anyone know if it's possible to use subforms in a Zoho CRM custom app? I'm building a sales reporting module which will be quite similar to the quote module in Zoho CRM (which has a subformy style interface) but be higher level (product categories rather than individual products) and contain different information (needs to have revenue + profit margin for each line item). 

I want the user to be able to add an unlimited number of product categories. E.g. they might add these rows

- Servers (revenue = $1000, gross profit = $500)

- Toner (revenue = $700, gross profit = $300)

I will then report on it so we can see:

- gross profit projections for each of the product types

- revenue projections for each of the product types

Unless I am mistaken, it is not possible to do reporting on line items within a quote otherwise I would use quotes for this use case.
