PayPal products with budget item

Hi, I have created my forms and linked them to paypal.  Now, how can I add budget items to the different products?  Ideally, this information would not be seen by the customer and would be available in paypal.

Thank you in advance!

To clarify, do you want to add a product only in PayPal only?

Can you please explain further the "budget items"?

When your form is submitted and redirected to PayPal, only the chosen product in form would be shown in PayPal.

Looking forward for your response.
