Hey! I am not on my comp so I can't take screenshots, but heres how you can do it using GUI's only:
Event:
Unit - A unit acquires an item
----------------------------------------------
Condition:
Item class of (Item being manipulated) equal to Miscellaneous
----------------------------------------------
Action 1:
If (All conditions are True) then do (Then Actions) else do (Else Actions)
If Condition 1:
Item class of (Item carried by (Hero Manipulating Item) in slot 1) equal to Miscellaneous
If Condition 2:
Item class of (Item carried by (Hero Manipulating Item) in slot 2) equal to Miscellaneous
Then Actions:
Item - Move (Item being Manipulated) to position of (Hero manipulating item))
Else Actions:
Do nothing
----------------------------------------------
Action 2:
If (All conditions are True) then do (Then Actions) else do (Else Actions)
If Condition 1:
Item class of (Item carried by (Hero Manipulating Item) in slot 1) equal to Miscellaneous
If Condition 2:
Item class of (Item carried by (Hero Manipulating Item) in slot 3) equal to Miscellaneous
Then Actions:
Item - Move (Item being Manipulated) to position of (Hero manipulating item))
Else Actions:
Do nothing
----------------------------------------------
Action 3:
If (All conditions are True) then do (Then Actions) else do (Else Actions)
If Condition 1:
Item class of (Item carried by (Hero Manipulating Item) in slot 1) equal to Miscellaneous
If Condition 2:
Item class of (Item carried by (Hero Manipulating Item) in slot 4) equal to Miscellaneous
Then Actions:
Item - Move (Item being Manipulated) to position of (Hero manipulating item))
Else Actions:
Do nothing
----------------------------------------------
And so on, doing every 2 slots possible at once in the inventory (1-2 , 1-3 , 1-4 , 1-5 , 1-6 , 2-3 , 2-4 , 2-5 , 2-6 , 3-4 , 3-5 , 3-6 , 4-5 , 4-6 , 5-6 (15 possible combination's, since 1-6 = 6-1, etc.)
It doesn't take very long if you copy paste the: If (All conditions are True) then do (Then Actions) else do (Else Actions)
Then you can do it with every "Item Class" (Permanent, Miscellaneous, Charged, etc.) allowing you to have 7 different types of item where you can only have 1 of each.
Hope this helps!
