Creating shortcut for a shell script in the Webui?

I'm looking to create some simple shortcuts (ideally buttons) in the Webui which I could link to a simple shell script or command which sets a couple specific webcam exposure/contrast setting to better accomodate the color of filament I'm using.
Right now I have to SSH to the rpi which is kind of tedious.

Is there any built in way to do this?

couple of ways. you could use system commands and add items to the system menu where shutdown/restart commands are. Or a combination of system gcode commands plugin and link a custom gcode to a custom control.
