Where are pattern fills 25-40 in Visio 2013

[lsearle]

Our company just upgraded to Visio 2013. We created our engineering process flowsheets in an earlier version and used pattern fills 25-40 to shade the shapes. But Visio 2013 pattern fills are only numbered 2-24; reserving 25-40 for gradient patterns.

Is there a way to import the (bitmap) pattern fills 25-40 from the old Visio into the Visio 2013? Or is our only option to select a similar gradient pattern?
