Option for Weapon Swap to keep/persist the Off-Hand

Weapon swap enables different setups, for example a general clear setup vs a bossing setup.

However, oftentimes it's a matter of the weapon being swapped and the offhand could just stay the same, be it a shield or a quiver; probably not dual-wielding though.

That's why I think an optional checkbox could help out. Be it next to I/II weapon swap symbols in inventory, or in Settings menu as an "Keep the off-hand while weapon swapping if the second set has a free off-hand slot."

As it is right now two-handed weapons can use it fully, but weapon+off-hand setups require either having a pair of well-crafted off-hands or manually switching things up.

Since we have a weapon swap in game already we could as well get an option to use it more conveniently?
