Set "Allow Bulk Edit" on the grid on dialog "Add Sub Assembly"

Hi,

I am fairly new to the Frappe framework and the ERPNext world.
My requirement is, when I click on the “Add Sub Assembly” button on the tree view of BoM,

A Dialog gets open with a grid having a button “Add Row” in there. Actually I need to add around 100 items for one sub assembly, it’s really difficult for me; to insert all 100 items manually.

So I was hoping, if we can bring the buttons “Upload” and “Download” somehow; so that I can upload all the items in one go that would be great.

As I checked Dialog code in frappe; it seems this form is defined through Client side code; and not a doctype.

Can anyone please help me to set “Allow Bulk Edit” on this dialog so that I can see upload and download buttons on this screen?

Thanks

I need Download and Upload buttons below this screen, as if bulk edit is enabled on this grid.
