Keep custom key between maps

[Aeddes]

Hello.

Is there any way to keep a custom keycard between maps?

I'm creating a WAD with three normal maps and one secret map.
At map 02, the secret exit goes to map31, and from MAP31, normal exit go to map 03.

What i'm looking for is: if player find the secret exit at map 2, will got a specific key (custom key) at MAP31 and keep it to use at map 3 for an alternative end.

I've found this: +INVENTORY.PERSISTENTPOWER, but didn't work on the custom key.

Doom 2 IWAD, UDMF.

Any help appreciated.

Thanks in advance.

That's just for powerups. What you want, instead, is Inventory.InterHubAmount (set it to 1).
