For temporary use maybe you could just use a small wedge in one of the slots of the column. Would not have to be super tight on account of the counterbalance spring and friction.

For the studio stands that I build, I have designed a pawl which is weighted to use gravity to always swing it towards engagement. Raising the camera, the pawl automatically disengages as it encounters each tooth. ("click, click, click" on the way up) It has a thin handle at the top allowing you to hold it out of engagement as you lower the camera.
The pawl has to match the pitch of the rack gear, and the center of the axis of rotation has to be the right "height" above the rack.
You would probably just want to make a stout bracket just for the pawl, and not overload the stand since the pawl would be supported on one side only.
I can send you a picture of what I do so you can show it to your local machinist. PM me your email address.
