Is it possible to modify the number of carriers a pinch pleat track has? We have a 224" track where the drapery manufacturer is asking for 80 carriers (they are saying it is a 2.25 drape). Yet entering this centre draw track into my projects results in 62 carriers @ 2.5 and 72 @ 3x. With a blackout fabric, can I add 80? Does the number of carriers listed in my projects include the master carrier?

Thank you.
