Forte Software Ideas

the program needs to have custom made sizes for roof or floor joists design. let say we have existing 2x6@24"o.c. roof rafters. we are vaulting this roof and need to add new 2x10 roof rafters i need to combine the two sizes to make it work. the program does not have two different sizes working together. we need to have that otherwise i have use two new bigger sizes and it becomes expensive. as an example i need to be able to combine the existing 2x6 with new 2x10 to make it work other wise i have add 2 new 2x10 rafters. this become expensive. please let me know if you have this option in the program, if you don't, can you add this feature !!!
