Customization in PDF templates for custom modules

Customization in PDF templates for custom modules

I'm facing some difficulties when it comes to the custom modules in zoho books:

1) Is there any way to get the item table field for my custom module? It doesn't show up in the dropdown when trying to add a new field.

2) I was trying to somehow get 1) to work so that the item table could successfully show up in the my custom PDF template for my custom module. I implemented a workaround by linking a custom zoho creator app to my books account and adding the items with their respective quantities in a particular string format. The customization options for the PDF template only include the header/footer. I couldn't find anything to do with changing the display format of the fields in the custom module or a 'table' option similar to the one in the customization screen for the purchase order template. Ultimately, I want this custom module template to be a clone of the purchase order template... but it seems this isn't possible according to the displayed options in the 'Clone' dropdown.

Any alternatives or fixes?
