Have a factory be able to assist a engineer

Something i liked in planetary annihilation is having a factory be able to assist a engineer and have all newly created engineers and units assist the targeted engineer.

Would this be helpful to add?

Never Fear, A Geek is Here!

Absolutely, not just for engineers.

If you could assist to a military unit too then you sort of have a mobile army waypoint where a factory can just reinforce an army wherever it is
