Can navigation stack switch a map ? [closed]

edit

Hi, everyone.

I'd like to switch a static map when the robot go to a place out of a loaded map.

Has navigation stack already supported a switching map feature ?
If yes, how can I use it ?

I think that when switching a map, I will have to do some additional processes,
such as initialization or transformation and it looks messy.
If possible, I'd like to use an existing one.

Thanks in advance.
