Blueprint: Putting a Tickbox next to a Variable in Details Panel

I’m trying to create a neat interface for controlling a clock.
I have

  1. Both Hands Rotating at Random (True/False)
  2. Manual Control Long Hand (Float)
  3. Manual Control Short Hand (Float)

Is it possible to put a tickbox on “Random Rotation” right next to the Manual Controls?
I’ve seen this on the lighting settings for other objects in the UE4 Editor so I feel it must be possible, I just don’t know how to ask it.

And another extra question while I’m at it, is it possible to GREY OUT the variables if the tickbox is true? so that I can’t edit the value until its ticked as false?

Thanks

I would also like to know if this is possible using only blueprints.
