Subforms in a webform?

Subforms in a webform?

Hello,

I am trying to create a webform that can be used for my own quoting purposes. 
I created a custom module for this, in the module is has all the details I would like in the form, but in the module I created a subform section for details of each item that I will be providing a quote on. 

Example of one subform: (in Crm module)

ITEM 1 |  ITEM 1 COLOUR | ITEM 1 NOTES 


I would like to be able to have ITEM1 options in the webform that will link to these in the module. However, I am unable to add a subform in the webform section? The reason I would like a subform is the ability to add more then 1 row.

Can I do this?

Thank you in advance
