Item Property Values as a Variable Request

I am not sure if this is available or not, but if it is not, it would be helpful to gain access to the formula result from one item property to be used in another. Maybe the result is a default variable name that just starts with 1 and increments by 1 for each new formula created for all subsequent item properties but with the ability to rename it with a unique name. In my example I have calculated that we need 95YD of wallcovering. I need to then use this value to calculate the labor cost for installation.
