create build -> add racks dialog is confusing

[karenetheridge]

When adding racks to a new build --

does it make sense to list validated racks specifically (and I'm not sure what criteria you are using for determining this -- as "validated" is not a field on the rack table), as normally one would be creating a new build to add racks and devices to, where these items have not yet been preflighted.

@perigrin what do you think?

So maybe "search for rack", and "added racks" respectively?
