Can you change the appearance of a synth knob?

I cannot find any documentation for the synth knob UMG widget ANYWHERE, and I couldn’t find any options to change its style to, for example, just set it as a plain circle or as some kind of polygon instead of the wacky style it has. If you literally can’t change this, is there a good alternative to allowing the user to turn a knob and detect when it is in a certain position?

Thanks in advance!

I might be a bit late to the party, but in case anyone ever finds this: there’s a Style group of settings for the synth knob where you can simply change the textures used. Also, there’s a Blueprint block called Make SynthKnobStyle in case you want to modify it from Blueprint.
