Hi Amibdr,
its not possible in standard CRM, reason being in ideal business cases you either create a pricelist on time basis for e.g. annually, quarterly which includes all your products or you create a pricelist based on some regions for e.g. pricelist for North America; it makes things easier for any user to work upon opportunities.
Through customization you can achieve your requirement but it might get confusing for users.
I would suggest to use the default functionality.
You can further elaborate your requirement, we might help you.
