Did you really mean FTM12 (from several years ago), or the current version: FTM2012?
In days gone by, this was referred to as an "Ahnentafel Table".
I miss that format as well and have made it one of my annual enhancement requests.
This format presents one line to an ancestor, with possible columns to present info on that same line, like date and place of birth and whatever else might fit on one line.
I encourage you to also make such an enhancement request - the more people requesting it may mean the more likely they will listen.
In the meantime, about all we can do is:
1) try to strip all we can from the current Ahnentafel report - don't include children, don't include facts and such. But notice that name, birth, death and marriage facts cannot be removed from this format.
2) Develop a custom report around a Custom Fact for ahnentafel numbers. Custom Reports can be exported as a spreadsheet, one record to a line.
