SAP MDG Vendor mass processing fiori app - adding vendor text field during EDIT phase

Hi all , I am looking for some guidance on how to approach this enhancement. We are running mass change vendor fiori app for BP/vendor for MDG. I got a requirement to add vendor text(comment) field so users can update this during mass change.

Is this possible add this text column through mostly configuration as shown below? if so, can someone provide some guidance?

or do I need get some UI5 involved to add this field?

This is the read_text field for ID = 0003 as shown below.

This is the text that can be retrive through FM READ_TEXT as shown in screenshot.
