The ability to save targets in mulitplayer battles

I did some search, and didn't find a similar thread so I'm making one to share my idea/suggestion.

I'm pretty sure we all have experience this when we have been farming or trophy hunting, atleast I have. You are continuous hiting the next button, searching for a village with good loot/trophies suitable for your army composition to attack. Suddenly you stuble over a village with amazing loot! :eek:

Your pulse rises while you scout the village to check if you have any chance to beat it... But only to find out that your troop composition doesn't fit the base at all!*sigh :(* But the village have some weaknesses that you know you could take advantage of, but only if you had the right troops.

Disapointed you look after the next button, your finger hits it... and you see the perfect village disapears in the skies.

I'm sure that every clasher have been in a scenario like this, if you haven't toss me in the River! ;)
Everytime after I have been trough a scenario like this, it think *what if I could save the village as target, and come back later?*

Many players want the ability to save different base layouts for War, Farming and Trophy hunting. why shouldn't we have the ability to save targets in multiplayer too?

I'm making a Pros and Cons list, How to prevent abuse and i would like you guys to tell me what you think of this idea and what you think should be on that list. Feedback please! :o
