Network Transform interpolation target prevents flip character ( y axis 180 degrees)

Options

Hey everyone, My players visual representation is a "Spine sekeletonAnimation" Component.

When I try to use networkTransform and select my spine for InterpolationTarget, its rotation axises etc cannot be modified manually ( ie: flip object y rot: 180 ). And if I select another empty gameobject inside player prefab, there are some glitces when interpolating. So what is the best practice to achieve this?
