parenting tool that lets you change the materials/colors?

Can someone give me a parenting tool that lets you fucking change the god damn material after you’ve parented a prop? cause Im fucking tired of parenting half a fucking TANK and then finding out that I can’t change the god damn materials on it. none of the parenting tools that I’ve found let you do shit with a prop once it’s parented.

You can’t touch the prop once it’s parented, Source does that, not the tools
