add a quick way to access lattice cage for each metaball object

if there is a quick and easy way to edit a lattice cage for each metaball object, that will be more flexible when using metaball for block out. Of course it will be a nightmare if adding lattice modifier one by one for each of the metaball (even though this is not allow) ,so i suggest a quick and intuitive way to have that,For example ,maybe double click on a metaball to bring the cage out and double click it when finished........
