Disable multiple invoice merge

Hi all,

When a user select multiple invoices to pay (click on pay all invoices) then a new invoice is generating with all these invoices included (merged) but there are also marked as paid the selected invoices each one separately.

For example I have unpaid invoice 1, 2 and 3.
When the user select all of them to pay there are 4 invoices marked as paid, 1,2,3 and 4 which includes all the selected (1,2 and 3).

Is there a way to disable this merge?

Thanks
