Is it possible to create a Revit family that automatically generates something from an instance parameter?

Strange question. Let me elaborate. I'm working to create a Revit family for a running track for work. The tricky part is I'm trying to make it as customizable as possible so that I can just change parameters when I load it into a project, and this includes the number of tracks, whether I need 6 tracks or 8. I'm wondering if it's possible to make a parameter that can automatically create the number of tracks I need in the project without copying the extrusion and just adjusting it to fit the previous track. I've tried playing with visibility graphics, array and offset tricks but nothing seems to work. Any tips would be immensely helpful.

@pfarsonAA4ZQ, #1. You're in the Revit Ideas forum and your post seems to be a question rather than an Idea.

#2. Couple different ways to do this for the track surface itself.   A.  Your extrusion would be locked to reference planes and those planes would be what would adjust the size.  You'll need a formula, that states that for x lanes, y amount of width is required per lane.  Your radii would need to be based off of the same thing.  B. Second option would be to run a sweep as the inside edge of the track and then the width of the sweep would be based on the same formula(s) and would adjust outward.  

Now the lane markers would be a slightly different story.  I'd suspect that the best way to do those would be to use sweeps again, but I'm not positive.  I'd have to play with it, but I'm wondering if arrays could help in this case.  

@kimberly_fuhrman-jones, could you please take this post over to the Revit Architecture forum?  Thank you!
