editing ticket design question

Hi everyone,

I am playing around with ticket designs, and I just don't remember the answer to this question so I thought I'd ask here - if I add a new design element to a boca ticket design, do I also HAVE to include it in the corresponding PAH design, or can I leave it off?  

Just for background - We're using recipient more and more on ticket sub lineitems, and I created a user-designed element (lovingly borrowed code that I found on an old community post!) that will print recipient sort name on the ticket, or if no recipient, the owner sort name.  We don't need that on PAH tickets, but I couldn't remember if the PAH would fail if there was a new element on the boca design that didn't make it to the corresponding PAH.

Thanks!
Kathleen
