create new bill in tray online

Hi, Team,

Just want to know how to change option when I try to pay bill from in tray.

In desktop version, when I create new bill, it directly link to purchase order interface, so I can have promised date when I schedule payment.

However, in tray online version it do not have that option for me to process invoices through purchase order, rather, default option is create bill. That do not have promised date for an invoice.

Can you have a look and advise?

Thanks.
