Multiple order by selection options in Query builder

I would like to have multiple order by selection options in the query builder.
Specifically, I would like to sort by the order of the numeric fields in the post meta, and then randomly within that order.

Yep, this would be great!
After ordering for a custom date field (primary) I would like to order for post title (secondary).

@Louis is the team planning to get this thing coming in near future?

This is a very important feature as when we build a complex listing site, this is a must-have.

Normally you will want to order by a lot of different factors, such as date, custom date, title, or to go even further, post likes, upvotes, post types, etc. or to go even even deeper, gives admin control by stick a post to the top (a custom field factor) as well as not affecting the general ordering.
