does anybody know if there is any possibility to link one or multiple

this would allow to keep some selected files perfectly aligned among
different releases of the same developed product, while allowing to
branch files that have to be different from version x to version
x+1.

If I am interpreting you correctly, you want to mark certain files so
that if a change to the file is delivered to a stream, then the same
change automatically shows up in other streams without any user having
to do anything.

If that's what you want, then you can't do that in RTC. Doing that for
arbitrary files would violate some of the assumptions on which RTC SCM
is built, such as the integrity of change sets.

If all the files that need to be kept in sync can be gathered together
in one SCM component, then you could do the following: Maintain those
file in a central place, such as a stream that includes only that one
component. All other streams would regularly replace the component with
the baseline of that component from the central stream. There are some
manual steps in there, but it will keep those files in sync across your
several streams.

If the files are scattered throughout your source and can't be gathered
into a single SCM component, then I can't think of a good way to keep
them in sync.
