At first, I would start with something like this. It's a snippet of code for my off brand origins mod, specifically the Shulk. What it does is it opens an inventory for the player to put items in, like post-mortem chest/ keep inventory.

command /ú:
    trigger:
        player is {SHK}
        open virtual chest inventory with size 1 named "Death Pocket" to player
        set {_slot} to 0
        loop 9 times:
            set slot {_slot} of player's current inventory to {SHKI::%{_slot}%}
            add 1 to {_slot}

on inventory close:
    if name of player's current inventory is "Death Pocket":
        set {_slot} to 0
        loop 9 times:
            set {SHKI::%{_slot}%} to slot {_slot} of player's current inventory
            add 1 to {_slot}

You can leave out the "player is {SHK}" part tho, that is to validate if player is the shulk in the first place- something you don't worry about since I recon you want the thing for everyone.
Next you'll probably want to somehow link the "on pick up:" event to this GUI for it to filter the items into specific slots, but I would lie to you if I said that I can help you with that. You could try comparing picked up items with every slot of GUI until you find a match and putting it into the coresponding slot number.
Hope I helped with something at least.
