You are essentially wanting the item to have 2 separate sets of charges (1 for alert self and 3 for other 2 spells), and items can't track mutiple charge types. There might be at least a work around after the revamp, but for know, I can't think of any way to do this.
I'm creating a magic item that has 3 spell charges that can be used between 2 spells that reset at dawn.
But I wanted to add Alert Self to the item that would be single use per long rest.
However, when I try to add AS I can only choose min-max charges.
I'm fine changing dawn to Long Rest, that's not an issue, but I'm not sure that that solves my problem

I thought that was the case, thanks for an answer at least :)
