No, but you can re-use the same field names and get the same data before
using <<Next record>>.

For example if you want 4 copies of the same card per page, you can set up
the page as if it were going to print 4 different records per page, then
remove all the <<Next record>> fields.

If you need more than 4 copies - for example 8 copies of each card - copy
page one of your mail merge main document and paste it to the end of the
document. Then you have a two-page layout that will do eight identical cards
at a time if you don't use any <<Next record>> fields.

If you're printing double-sided, things are different and you need to know
what sequence the pages are going to be printed in.
