Having to restock NPC Thrall Archers- brutal

[ConanTheCook]

btw another related thread is here:

Since Archers now need Arrows, how about an arrow box?

I recognized that Archers now need Arrows if they should use other Ammo than Flinthead Arrows. So how about an Arrow Box for Thralls like an Thrall Pot for Food? Because it can be very time-consuming to check hundreds of thralls in lots of different Buildings across the map.
