Automatically add (fix price) to an exist (Pricelist) when selling

I am moving from Odoo to ERPNext, and i have a question about customizing ERPNext.

Can we customize the pricelist?

in a way that pricelist will automatically be created for that customer when changing the product price on the quotation or invoice.

normal process:

create sale = add customer = pircelist exist = add products = products pricelist exist

special customization:

create sale = add customer = pircelist exist = add products = add fix prices = fix price automatically added the customer pricelist
