Cut list of the whole project?

Hello,

I am quite inexperienced since i am using solidworks only for 1 year including studies, so i wanted to ask if it is possible to have all weldment cut lists parts to be calculated. For ex. we doing railings and one projects comes with 20-30 different dimensions, but sometimes there are same parts in one wielded part like filling *ex. 12 diameter tube) it is usable in all project and sometimes they are the same. so is it possible to have them calculated or you have to do assembly file from different wielded parts than put them in sub-assembly and after that in one general assembly.
