How to change Drag Script to target specific part?

Hi,

I have a script in the ServerScriptService:

local re= game.ReplicatedStorage:WaitForChild('RemoteEvent')

re.OnServerEvent:connect(function(plr,reason,target,pos)
    if reason == 'Drag' then
        target.CFrame= CFrame.new(pos)
    end
    end)

Also, a LocalScript in the StarterGUI

local re= game.ReplicatedStorage:WaitForChild('RemoteEvent')
local player= game.Players.LocalPlayer
local mouse= player:GetMouse()
local target, drag 



mouse.Move:connect(function()

    if target and drag then
        re:FireServer('Drag',target,mouse.Hit.p)
    end
end)



mouse.Button1Down:connect(function()
    if mouse.Target then
    drag= true
    target= mouse.Target
    end
end)

mouse.Button1Up:connect(function()
    drag= false
    target= nil
    mouse.TargetFilter= nil
end)

My question is, how would I amend these scripts to target specific parts?

Do I need to set a new script in the part or, maybe, can I add a new variable to the StarterGUI script? I would like the RemoteEvent to trigger many different part individually, so I was thinking about putting the "draggable parts" in a folder in the Workspace.

Thank you for your help!
