Multiple Column text field in Static PDF form

Okay, I'm pulling my hair out here. I am filling a .pdf form with itextsharp using powershell scripts. All this part of the issue is working fine.

My problem is that I have the following data:

A3015400R-2,A3015318R-1,A3015318R-2,A3015336R-1,A3015423R-1,A3015423R- 2,A3015486R-1,A3015306R-1,A3015240R-1,A3015102R-1,A3015333R-1,A3015120 R-1,A3015158R-1,A3015333R-1,A3015400R-3,A3015400R-6,A3015400R-7,A30152 34R-1,A3015234R-2,A3015400R-9,A3015306R-5,A3015311R-1,A3015400R-2,A301 5318R-1,A3015318R-2,A3015336R-1,A3015423R-1,A3015423R-2,A3015486R-1,A3 015306R-1,A3015240R-1,A3015102R-1,A3015333R-1,A3015120R-1,A3015158R-1, A3015333R-1,A3015400R-3,A3015400R-6,A3015400R-7,A3015234R-1,A3015234R- 2,A3015400R-9,A3015306R-5,A3015311R-1

That I would like to be displayed in columns across the page within one text field. So that the text field would look like this (approximately):

I have the data sorted before I populate, so they go in numerical order, and i would like the be able to read them from top to bottom, left to right.

I just can't figure out how to either:

a) add multiple columns like I add multiple lines inside a text field

or

b) have multiple text fields linked together to thread the text input from fieldA to fieldB

Any help would be much appreciated.

edit: The data is actually in this format:
