Summoning questions.

[KnTenshi]

I'm making a mod nation that nearly exclusively relies on Ritual Summoning and domsummon for units. I've hit a few snags because of this.

1. I want to have a unit domsummon a randomized assortment of units. I though just naming them all the same and having the command #domsummon "Xenomorph Warrior" would summon any units named Xenomorph Warrior, but this apparently isn't the case. Is there a way to do this, i.e. have a unit summon a random unit, such as Pangaea's Manikins?

2. Is there a way to have domsummon2/domsummon20 round down the number it rolls so that it does not always summon a unit? I'll admit to not truly testing out domsummon20, but domsummon2 always produces a unit, even in a one candle province.

3. In testing a stealthy summoner, I've found that summoning happens in this order: Summoned unit(s) appear and are placed in the garrison, if the summoner has any troops and can command more, the summoned unit is then placed in the first squad. The problem I have with this is that whenever a stealthed unit summons another in an enemy province, the unit is instantly spotted and likely killed. Is there any way around this?
