now when i add products in opportunities or leads, it does not give me option to choose price list, what it does is, if the lead has Canada address, it simply take the full USD and show it as canada pricing.

Rather - this is what i need-:

1. When i add the product in crm - it should give me an option to choose price list (like salesforce does), and then i can select the product in specific price list.

2. I prefer keeping zoho books as base for adding new products, as it syncs with zoho crm (this one is working btw), i need help with point number 1
