CRM 5.2.1.6 End of Export String - Record Count?

We use CRM 5.2.1.6 and for a specific abnormal campaign, we wish to replace the standard EOE (End Of Export String) with a trailer record. The minimum we require is a record count although the full trailer, if possible is:
Record Type,Physical Count,Logical Count, Filler e.g.

9|000099999|000099999|Filler of 141 spaces
Record counts should be 9 characters left padded with zeros.
The | is not required as this will be a fixed width file and is there purely to denote field separations.

I would be grateful for any help, even if it is a "sorry can't be done".

Thanks
Mark
