Custom option for unlimited equipment use?

Could we please get an option for custom modes that makes equipment unlimited, on a cooldown, like in the campaign, instead of limited-use and disposable?
This way, for example, one could set up a mode as similar to Halo 5 as possible, using unlimited Thruster.
Or, you know, there’s some obvious silly mode ideas that could use all melee weapons and unlimited Repulsor, etc etc
Kinda surprised the option isn’t there already
