Instead of sleeping, I ended up thinking on a suggestion, based on the Fallout 4 bells.

Basically there would be a bell or another kind of instrument-item-thing that produces sound, like those Asian bell plates. The bell can be sound by right-clicking or by sending a redstone signal to it.

The bell, when rung, serves as a rally point for your hired NPCs. So, while holding the bell in your hands and right-clicking on a Table of Command, you can assign a squad to it. For example, each time the bell from squad "DANKEST PLATOON" is rang, all NPCs assigned to that squad, provided they are on the radius of the bell (how many blocks could it be, btw?), will come running to it.

If there were no NPCs to fight, your squad would stand idle for some moments. If nothing happens, they would return to their previous assigned task.

Here are some practical uses for this feature:

-> Your NPCs are patrolling your castle, and you suddenly find yourself under siege by an enemy invasion and you have no idea where you stored your horns of command. Well, ring your bell and your NPCs will come running to your raid.

-> It can also be used as a trap. Put a bell in the entrance of your hidden base and attach a tripwire hook to it. Once an enemy NPC or player trigger the tripwire, the bell will ring and your NPCs will surprise the trespasser.
