Creating Bulk Bills

Creating Bulk Bills

Hello

i receive invoices from Suppliers and i make them payment after 15 or 30 days 

say they are 30 or 40 Invoices which i need to pay them after creating Bills and then Record Payments

i need to know how to create bill in Bulk as i do not want to create single bill for 40 invoices as its time consuming

to record bulk payment i have seen that you have a option for Bulk payment but i cannot find any option for Bulk Bill recording.

thank you
