Part families for standard parts having large number of variants

Hi everyone,

i have a parametric data for standard part contains large number of instances for a particular dimension.It's bit difficult to use spread sheet to create part families or .krx file for such large num of variants.i thought PTS author can help me here.But if a person can't have licensed version, can't use that i dropped.
Is there any way to create such instances?

here the example part -

I am using NX 8.5.

Thanks in advance.
