Is there a way to have Sim DriveLine blocks utilize a table of non-constant friction data, or can they only use constant friction data set in the block's parameters?

I have a table of collected data for accurate friction. Is there a way to include this in a Simscape Driveline model, or would it require calculating the force from a look-up table and then using ideal force and torque sources applied to Simscape Multibody joints.
Thanks,

There are a number of nonlinear blocks that would allow you to specify a nonlinear relationship for friction.
This block lets you define a lookup table to have a nonlinear relationship between speed and viscous friction
This block lets you vary the damping coefficient with any nonlinear relationship between any quantities you can measure
Similar blocks exist for translational mechanical systems.
