Moving peg's keyframes along with deformers' ones


I already animated movement of a character on a peg layer, and then I animated legs with bone deformer. Now i need to change timing on the peg layer. The question is: is there any way to link peg and deformation layer in a way I could move keyframes on a peg layer, and corresponding keyframes of deformation layer would follow this changing automatically?

If you collapse the peg layer (Torso-P), you move everything inside.

Thank you! It was easy)
