When I'm done terra forming Mars, I usually end up with 10s of thousands of infrastructure, which is nice to have for sure, but I'm usually just shipping out a "Starting Package" to Colonies and forget about it.
Now, infra is made by civilians and shipped to where demand is, which feels natural enough and they do a pretty good job at this.
Add to this a button and ability to turn over an amount of infrastructure to the civilians and let them sort it out by demand.
Also useful for LG Infra, which is in high demand, but made much slower by civilians because LG Colonies tend to grow slower. Would let the player just build LG Infra, hand it over, and civilian companies carry it to where the demand is.
