Hi, I just wanted to ask if there's a way to combine existing sub-assemblies into a single top-level (full) assembly.

For example:

Top/Full Assembly name :Box_Cust

Sub-assemblies: 

 Box_1_Side`

 Box_2_Front`

 Box_3_Top`

Each of these sub-assemblies already contains the required panels and bill of materials.

Is there a way to combine these existing sub-assemblies under one top/full assembly (`Box_Cust`) so that when I run the job, I only need to select the top/full assembly instead of each sub-assembly individually?

I hope that makes sense. Thanks in advance for any advice!
