Is it possible to mark for example the 10th label when printing labels through pdf?

Hi guys,

For my job I'm wondering whether it's possible to print a marking or maybe even something numeric on every 10th label.

We print them via PDF and sometimes we have some labels left at the end of a delivery, indicating that we forgot to label something.

I'd like to make sure that doesn't happen anymore and I think having a marker on every 10th label would help with that, as it becomes more visible (we work with full boxes of 10 or 20 pcs).

Thanks in advance for the replies.
