Adding covertec button to generic saber

I'm looking to submit a generic jedi (prequel trilogy) to Rebel Legion. Those standards require a covertec clip, which I have. Now I'm looking for a generic saber with covertec knob.

I recently had a good experience ordering a Qui-Gon hilt from TXQSABER, so I checked that store. It appears that all of the hilts with covertec knobs are replica hilts for named characters. I checked a couple other vendors in the buyer's guide and I am not seeing any non-named character hilts that also have covertec knobs.

I recently saw this saber recommended here, and I see the shop has covertec knobs, but not on this saber:

I am not picky about baselit vs neopixel or anything, except I want a RL-qualifiable hilt with a covertec knob. I'd be grateful for any advice.
