You will need to use one object as your base and convert the other objects to a mesh and add the mesh as a limb to the base object. You will then need to apply the texture to the limb. When all objects are added save the object. Here is a quick demo. The images are just solid colors.

autocam off
position camera 0, 0, -50
load image "Cyan.png", 1

make object box 1, 10, 10, 1

make mesh from object 1, 1
add limb 1, 1, 1
delete mesh 1
offset limb 1, 0, -5, 0, 0
offset limb 1, 1, 5, 0, 0
texture limb 1, 1, 2

delete file "object.dbo"

save object "object.dbo", 1
