Flagging System For Clan War

WARNING: This is Long

Recently I've been in a clan where during clan war, we call out bases that we want to attack. What this means is that we call out the number next to the base we want to attack during clan war. (The number next to the player's name in the war map) We've been using this calling system for a lot of wars and it has been doing quite well for us. Although after using it for a while longer, it has been a hassle for the leaders and co-leaders to try and "write down" the bases that we have called out. It has been a hassle to the point where some people have been stealing other member's bases. For example: Let's say I call out #10 during the clan war preparations. This means that #10 is the base I am going to attack when clan war starts. (Clan War starts) I am getting my troops ready, and in the clan war map i see someone else attack the base that I have chosen. Now it irritates a lot of us because now we have to re-decide what base to attack and it is a hassle mainly because some people don't read clan mail, or get the memo and stuff of that matter. That person didn't know that I called out #10, so they possibly get kicked. We don't want this to happen. So it would mean a lot if you could make a Flagging System. What this "Flagging System" does is help players "flag" what bases they are planning to attack when clan war starts. There would be a button that says "Flag Base," upon pressing this button would create a symbol or something to help you know that said player flagged this base. Now it doesn't prevent players attacking it, but it instead gives better communications of who is attacking who. The main point of this idea is to help players know what bases people are planning to attack. Because Clash of Clans is an international game, there's no doubt people are playing on both sides of the world. A player might be on a COMPLETELY different time zone from everyone else. So that person might call out a base, but no one is there to write it down or notify people about it because not everyone is great at communicating the information. So if no one is there to record that specified base that player wanted, they could just "flag" that base and everyone else would know about it. Now I don't know how this plays out with multiple people wanting the same base, you could let all of them "flag" that one base. Other than that we don't know much past that point.
