GR Yaris Can you use the air compressor without the tyre goop?

[DogToy]

Just wondering if anybody has tried using the air compressor in the boot for adjusting pressures. If so, and the gauge is okay then I don't have to bring a separate one for if I want to fiddle with pressures at a track day.
The manual just talks about the procedure for using it to pump in the tyre goo and reinflate. I guess it can be used without the goo canister but is it any good?

Not tried on the GR, but can on both our other cars.

It has worked fine for me. The only challenge is getting the damn wire wrapped up neat enough to fit it back in its space!

Pressure shown on the gauge matches the tire monitoring screen too.
