Display unit range while using set target (T)

Sometimes i want to use set target to use units like recluse/crab ... to target the ground while moving.
This is especially useful when you try to decloak units which were visible before (Flea, bombs ...).

I would like to see the maximum range of the units i selected while using set target so i do not have to spam click in an approximated range and instead have some kind of indicator if the unit is even able to shoot there right now.

There's an option to do that. However, if you have a group of let's say puppies selected, the game becomes incredibly hard to read.
