@User there's no easy way to achieve this right now like you may be used to in Virtuoso. You need to add an ugly save line to your simulation setup:

.save all @M.x1.XMcas_p.msky130_fd_pr__pfet_01v8[vdsat]

For each parameter and each device. That will save the op values to the results file. The next step would be adding the annotations either to the symbol or next to the symbol. It slows me down a lot so I've got a TODO item to write a TCL script to pull out each of the devices and automatically place the op save commands in the netlist. I will post here once I get something working for others to use/improve although this will likely be sometime in July
