Looking for 3rd party spotter arms for Rogue Combo Rack (longer than stock)

I recently picked up the Rogue Combo Rack, but I’m finding the stock spotter arms (19.5") are a bit too short for comfort when squatting.

Since the combo rack uses that specific telescoping sleeve/drop-in design rather than standard 3x3 pin holes. Has anyone has found a "plug and play" solution or if custom is the only way to go.

Thanks!
