Mass Upload functionality for a custom table in ADT

[#1]

Hello Experts,

I’m trying to create a table in ADT and  generated an app from it to input data. I also want to add a mass upload functionality using Excel. I have a few questions regarding the best approach:

1. Can I implement the Excel upload without using BAS, by using actions in the Behavior Definition?

2. If I use BAS, can I start with a List Report template and later add the Excel upload functionality?

Could you please guide me on how this can be achieved?
