Focus sprite by leftclick and then remove focus by leftclick again. (C++ and SFML 2.2) - c++

Question

In the following code a sprite can by clicked with left mouse button and then moved around freely. Then you have to hit the right button to "free" it again.
Now what is, if I want to use left button for removing the focus, instead of right button. Is this possible and how? I can't imagine, how to do it. Many thanks in advance.

try this
if (leftclicked)
{
for (auto& enemy = EnemyVector.rbegin(); enemy != EnemyVector.rend(); ++enemy)
{
if (enemy->getGlobalBounds().contains(static_cast<float>(mousePos.x), static_cast<float>(mousePos.y)))
{
focus = &(*enemy);
move = !move;
break;
}
}
}
