Subcontractor Bidding Workflow

I self perform, meaning my employees perform 5% or less than all of our work. 95% of it is subcontracted. I need to be in the details of estimating for about 5% of things and then coordinate the big picture. I rely a lot on I've got a farm out bid packages, and then I'll receive, for example, electrical estimates from 4 different guys and be able to plug that into my bid. At present in builder trend, I can send out a scope to multiple subs at once and they can get me their price back. So I can log back in two weeks later and go, oh, look. I've got bids here from all. I can, manipulate them in some ways and then say, I'm selecting x sub. Boom, and it just imports their price to my estimate.
