Add the + features for troops training and spells

Please add the plus one features on troops training and spells. Just like how we have the "-" to deduct one troops or spell on the queue, but this time add a "+" to plus one troop in the queue. The reason for that is because if we want to add an additional troops in between the queue will be less click. I have always have problems where I have to remove all the troops that are already on queue to move up the one troop that I want to add back to the queue. This feature will help eliminate the struggle of having to minus all the troops that are already on queue to add the additional one unit to the troop that is already queued in the front. Let's say I have 3 wizards in the front and I want to add another wizard to make it 4 and I already my other troops that are on the queue behind the wizards. So not I have to remove all the troops the are on the queue behind the wizard to just add one more wizard or maybe more. Does that make sense?

Supercell had introduced a feature that would allow you to move troops around in your barracks and manage them more easily. There was a problem with it that created bigger issues and it had to be removed. At the time, they said they were working on a solution and would bring the feature back to the game in a future release. When it does, I think it'll resolve your issues.
