I am not aware of a feature like this in version 5. Also there sadly is no scripting API in eeschema for version 5.
Similar requests also were without resolution (recent example Eschema symbols off-grid, need to "snap all to grid") so i fear it is not easily fixable.
And yes this is a known problem and a solution is worked on (The true solution at least in my opinion is to have snap to objects instead of relying on grids plus maybe dynamic align tools similar to for example adobe indesign. The former for easily connecting wires to your pins and the later to still have nicely aligned symbols such that the schematic looks good overall even without the need for a grid.)
Are you sure? The fact that nobody openly complained about your wording is not an indication that they were ok with it. To be honest the response by wayne at least seems to indicate that he was at least slightly annoyed (it has a certain tone that i never encountered in any of his other responses).
