How to wake midpoints to use as constraints?

Midpoints will not wake unless I choose something new to draw e.g. a new line. I'd like to use constraints directly on midpoints but Onshape tells me; "A constraint must involve something from the sketch".

Did I miss something?

    @Firesale, you can place points on the midpoints of your rectangle sides, select them and then use a coincident constraint.

    I would first create a point at the mid of each of the 2 lines, select the 2 points and then use the coincident constraint.

    Or ...
    Create only 1 point at the mid of one of the 2 lines, select the point and the other line and then use the midpoint contraint.


    @derek_ward and @hakro
    Thanks, that works but I think the "wake midpoint" should be active on constraints also. Oh, and on Dimension also. A huge step-saver!
    Bottom line is; I don't see any good reason for putting it to sleep:)

    I'll "reject" the answers above because it seems that you can not wake the midpoints for this operation. The answers do explain the best alternative though :)
    I am sure there is a more complex reason for them not to wake. 

    BTW @hakro ; nice screen caps, do you use Snagit?

    @Firesale: No, I use Jing from TechSmith for screenshots and screenmovies..
