Adding a field to "Get Items from" dialog

Dear all, I want add another field to this form (to the marked area) from the opportunity doctype, any idea?

Thank you,

Go to Customize Form from the Awesome Bar, Input the name of the concerned Doctype and from their, you will be able to add the new field. Save the field and then use edit link, followed by “Move” to place the new field wherever you want it on the form.

Hi @Otunba, this is not related to a normal form but “Get Items from” dialog pop up which doesnt give any customization options. any idea?

In that case, I have no further idea.
