applying shear and tension

Dear LAMMPS Users,
I would like to apply shear strain (xy) and tensile strain in the x direction together at the same time to an atomistic system of gold. I know how to do each separately but it is important for me to be able to do them both at the same time. I sincerely appreciate any help and ideas.

Fix deform can do both.
