Counting via/contact in a certain area

Hi.  I am new to Calibre rule file making.

It is possible to check the number of via on metals?

 

Example: Check if at least two contacts(cc) are use between metal1 and metal2.

 

My idea

 

x = metal 1 AND metal 2 AND cc

y = metal 1 and metal 2 // this is the area with cc

z = compute area of y

area_cc = 0.78 //from design rule

 

if z/area_cc =>2 then no error

     else show error flag

 

how to implement this in calibre?

 

thanks in advance!
