Copy to Back - lifelike/countersheetsextension GitHub Wiki

Appending a > (greater than) sign after any header means that it will apply also to the back of the counter. So any value that should always be identical on both sides of counters will only have to appear in that column, without repeating a similar column for the back of the counters.

Adding BACK to a counter is not enough to actually make it have content on its back side. The extension must know of some template to use for that other side as well. If a template on the front of the counter should be used also for the back then the copy-to-back > sign must be appended to that template.

Alternatively, if you want a different template as the back, you use the + sign in a column header after BACK appears. In the + column the rows can specify a template for each counter. This is using the Combining Templates method, but specifically for the back.
