(first time posting, I just copied my heading and put it here)

Hello, I have a part template with global variables to make similar parts with different dimensions for the slots (or fingers). A problem I haven't solved yet it when the part has a different number of fingers. The template is set with 5 fingers and global variables to define length, width, height, separation distance, tolerance etc to make rapid changes. When a new part is needed to be modeled but has 8 fingers (any amount different than 5), I have to manually sketch in 3 more fingers, smart dimension to a global variable and then I can change my variables to produce the part. So my question is, using variables, or properties, can I create a template that has "number of finger" as an input? Instead of manually adding fingers to the sketch or having to creating multiple templates, each which will specify for a certain number of fingers? Thanks
