Laser cut path length for structural weldments

We are getting a new tubing laser cutter and our estimating software estimates by linear inches of cut.  Is there a way to add linear inches of cut to a structural weldment or at worst case a solid body for tubing?  I really hope this is not a manually entered information, this will be a nightmare for ECR/revisions.

 

Side note, I know sheet metal has this feature, which we uses, just not sure how to get tubing to read the same.

 

Thanks,

Kyle
