How to change initial pose on a Control Rig?

Hello,

I have a character that I created a Control Rig for. The goal is to make the character sit in the vehicle and animate it procedurally. The only problem that I have is that I can’t figure out how to pose the Control rig - my character is currently in t-pose and I want him to be sitting in the vehicle.
I created a Control Rig Pose asset of a character sitting in Sequencer, but I can’t figure out how to transfer that pose to the initial pose of the Control Rig.
I played around with pose caching, but the documentation is sparse and I can’t figure out how it works (tried to set the Rig Pose variable in Construction event, Forward Solve, Post Forward solve, etc., but no matter what I do and on which event I put ‘Apply Pose Cache’ nothing changes, I tried all combinations of events I could think of, I tried looking online and asking AI, with no success).

So, whats the best way to get my character Control Rig into the desired initial pose so that I can proceed with procedural animations?

Cheers, Vid
