Magic weapon help

I want to make a weapon in DDBs system to use in my campaign, but im sort of stuck with the options available to me.

The weapon I want to make is a cursed artifact made by a god, with 4 different effects, of which only 1 can be active at a time and that choice for that effect must be made at the start of the day, or it loses any magical properties for the rest of that day, becoming a completely mundane weapon of the same type until the next dawn.

From what I understood in the homebrew creator, I can either make 4 different versions of the weapon as completely separate items or put the different effects in the description of the item only and leave any other section empty.  My issue here is that it seems the effects are either always applied automatically (when filling in the appropriate sections), or everything has to be done manually while playing, making it easy to forget to apply the weapon's effects.

Does anyone have a suggestion to make this idea work or am I stuck with the option I already see?

Unfortunately, the homebrew system doesn't really have any way to do what you're trying to do. It was originally designed to be able to replicate the sort of things that official magic items could do, but not much else; since there's nothing in any official material that has behavior anything like this, it wasn't something the designers foresaw as being something people might want.

Probably the best you can do is make four different versions of the item and just choose which one to use each day.
