Required feature: Sequential printing - but do all first layers.

Hey everyone,

I'm wondering why Sequential Printing doesn't also allow the option of printing the first layer of all objects first.

I've printed lots of sequential prints in a production environment, and I'm seeing a common issue that could be avoided. Normally, the first layer goes on perfect because it is laid down immediately after bed level sensing. However during a sequential print, that is only true for the first instance. The first layers of subsequent instances aren't guaranteed to adhere good because the bed shifts slightly over time because of heat. I see occasional failures,  and a lot of bad looking first layers because of this.

If the slicer had the option of laying down all of the first layers before starting sequential printing, this would fix the problem.

Edit: doing a quick google search, I see that this feature has been requested multiple times already by multiple people. One suggested the option of "print n layers first" and I think that's the most flexible solution. I also see that brims are already printed this way in sequential print mode, so the logic of that behavior should also apply to the object.
