Making a tile using Armos>Item appear with Secret Combos

[Nimono]

Is it possible to make a tile (eg., a Treasure Chest with the Slash combo) appear AND use the flag Armos>Item when you slash another Slash-combo tile that has a Secret Combo flag? Yes, confusing, but that was the only way I could think of to put it...

1) Set flag 79 (any sword) to the Slash combo (not the chest).
2) Set flag 16 (secret flag) to the Chest combo (this chest must not be a slash combo, I've experienced problems with it).
3) Set the sword secret combo (sword, white sword, magic sword, master sword) that will appear in the slash combo as normally.
4) Make an identical chest combo, but set this one as "slash".
5) Put the slashable chest in the secret combos menu, flag 16.
6) In the Secret combos menu, CTRL+click on secret tile 16 and select Armos->Item.
7) *Set the opened chest combo as an under combo.

When you slash the switch, the chest becomes slashable, and when you slash it, the secret item appears, I've just tried it and it worked.

*If you have another under combo, put it in secret combo 17, and the places where you want this under combo flagged as secret combo 17.
