Fill Summary Page from various cells across several sheets

Hi all,
I have a Workbook that I have created with a Summary page to view with data filed from all sheets in the work book, but just certain cells. My question is, without having to reference each cell manually, is there a way to copy from the "template" Sheet to the remaining 20 odd sheets?

Then if I create an new sheet, how do I get it referenced in the Summary sheet.

I have attached the file for reference.

Cheers,
