Synchronous editing of declaration/implementation of function/method

I know there is a way to rename both variables and types in Lazarus.
(It is F2)
It a useful feature, but what I also often want to do is to change
procedure header. And since its declaration must be the same both in
interface and implementation sections of the unit I always have to
edit it twice. And I still can not figure out the way to automate this
process in Lazarus. If there actually is such way at all. Well, if
there is no, I would be quite surprised because when I press
Ctrl+Shift+Up and Ctrl+Shift+Down it always detects correctly
corresponding procedure headers both for classes and separate
procedures and even if there are overloaded procedures/methods with
the same name. Ctrl+Shift+C sometimes correctly changes implementation
procedure header with accordance to interface procedure header, but it
is far from perfect and often creates duplicate implementations
instead of correcting existing ones. If you know what I mean...

So... How do I synchro-edit headers of my procedures in Lazarus?
Thank you for paying attention.

QuoteCtrl+Shift+C sometimes correctly changes implementation procedure
header with accordance to interface procedure header, but it is far
from perfect and often creates duplicate implementations instead of
correcting existing ones.Actually, this is the best it can do since
the heuristic cannot be perfect (it can be better than the current
implementation of course). It cannot know whether you accidentally
write a wrong parameter type only or you create a whole new procedure.

As for codetools: The best results will be if you do one procedure at
a time.

Such a Syncro Edit is currently not available. Nor planned (at least
not in near future).

Also Syncro edit is limited to one file, but declaration and
implementation can be in different files (include files).
But even, in a single file, it is a very specific use case, and a lot
of work to do...
