I need to import a file with new prices. When I'm importing a file with columns like that:

pricelist external id | product external id | variant external id | fixed price

I adds new lines to the pricelist instead of changing the existing ones. I also tried to use pricelist line external id like this:

pricelist_line external id | fixed price

But this does not work at all. It says it is missing pricelist name because it actually wants to create new pricelist...

How do I do this? Pricelist managament in Odoo is really painful.
