Bind multiple skill to one key

The thought is just allow one key to go through two different skills.

As more of a quality of life feel. Not an improvement to damage. Would only be 2 skills and wouldn't stop them from also being individually bound.

Examples:
Chaos witch casting contagion and then essence drain. one left click would start contagion and once complete directly go into the essence drain animation without the need to click the 2nd button.

Ranger looking to do barrage then any specific attack. In the event that barrage is on cooldown, it would just go into the attack as normal.

Reason:
When there are 1-2 skill builds that clear just as well as combo builds can, i would like to help incentivize setting up skill combos that may have been overlooked just because its hard to manage the keys/controls. If we are always going to cast a set of spells/attacks together why not allow them to do so with one button.
