Acumatica Mobile App - Minimize the Steps to Add Line Items in the GRID

Hi Everyone, 

We have a requirement involving a Form and Grid in the Mobile Application. Currently, adding a single line item requires about six steps (as listed below). If a user needs to add more than 20 lines, it results in a large number of clicks and becomes inefficient.

Is there a way to streamline this process or reduce the number of clicks required to add multiple lines?
