Custom prices for items in quotation


in the latest stable ERP version, individual prices can be set for an item in a quation, but these are reset to the default price when duplicating the quotation or changing the date field.
Is there any way to prevent this automatic updating?

Of course, new entries can be entered in the price list each time, but this is time-consuming and there should only be one standard price. However, an individual price can be negotiated per customer.

Thanks in advance!
