Feature Request: Alignment of multiline operator expressions

Sorry about spamming feature request lately! But I'm happy I've found a Lua-formatter/style checker that works for most of my needs! Here's something I do with my code often, and I wonder if this could be added as some kind of rule. I tend to align multiline statements that start with operators and here's the different usecases I do them:

Alignment in if-statements:

-- NOTE: Alignment of the first line in if statements that have multilines that begin with an operator.
-- The first expression is aligned with the first non-operator on the next line and so forth.
-- the operators are aligned too. note that "then" closes the if on multiline statements and is on it's first line
-- aligned with the "if":
if   true  and true
  or false and false
  or true
then
  print("Yay!")
end

-- NOTE: A case where one of the preceding operators is longer than others:
if    true  and true
  or  false and false
  not true
then
  print("Yay!")
end

Aligment on multine expressions inside brackets (and for example in a return).

-- NOTE: The first expression is aligned according to the first non-operator below it and so forth:
function foo()
  return (
      100
    * 123
    + 456
  )
end

And lastly in assigment where there's a hanging "="-sign:

package.path
  =  "./?.lua;./?/init.lua;"
  .. "./src/?.lua;./src/?/init.lua;"
  .. "./lib/?.lua;./lib/?/init.lua;"
  .. "./spec/?.lua;./spec/?/init.lua;"
  .. package.path
  
-- NOTE: Alternatively this:
package.path = 
     "./?.lua;./?/init.lua;"
  .. "./src/?.lua;./src/?/init.lua;"
  .. "./lib/?.lua;./lib/?/init.lua;"
  .. "./spec/?.lua;./spec/?/init.lua;"
  .. package.path

I understand if these are out of the scope for this stylechecker/formatter, but I tend to use these in a lot of my codebases and would really enjoy having them covered, but I understand if there are some tricky cornercases that make these difficult to implement!
