How to modify a custom check xml template to repeat check info when it is paying multiple invoices?

Hello

I am creating a custom xml template to create a check payment output file.  The output file will be fed into PayBase so it looks more like an EFT file than a check file as PayBase does the formatting.  I have the template working except for when multiple invoices are paid on one check.  In the layout of the file fed to PayBase,  each invoice line needs to have the check amount, number and vendor name. 

I will upload a document providing an example of what Ithe file should look like vs what my template is producting currently.

Any advice and/or any resources that may assist me would be truly appreciated.
