Change sales price before invoicing.
Currently, there are two options:
Change the price on the invoice.
Run a price update on that entry using "Transaction Price Update Journal" which only updates if there are changes in the sales pricelist
Three suggestions:
A new action to set a price manually in the invoice suggestion
A new action to set a price manually in the list of ledger entries
Enable the possibility to automatically create/include entries in the "Transaction Price Update Journal" even though there are no changes to the sales price setup
